Basketball is a team
sport in
which two teams of 5 players try to score points against one
another by placing a
ball through
a
10 foot (3.048 m) high
hoop (the
goal) under organized rules. Basketball is one
of the most popular and widely viewed sports in the
world.
Points are scored by throwing (shooting) the ball through the
basket from above. dunking and slamming the ball into the rim, or
any other acrobatic styles to make the ball into the basket from
any distance; the team with more points at the end of the game
wins, but additional time(overtime) may be issued when the scores
of both teams are the same. The ball can be advanced on the court
by bouncing it (
dribbling) or
passing it between teammates. Disruptive physical contact
(
foul) is
penalized and free throws will be issued if the player is fouled
while shooting the ball and there are restrictions on how the ball
can be handled (
violations).
Through time, basketball has developed to involve many common
techniques of shooting, passing and dribbling, as well as players'
positions, and offensive and defensive structures. Typically, the
tallest members of a team will play
center or one of two
forward positions, while shorter players or those who
possess the best ball handling skills and speed, play the
guard positions. While competitive basketball is carefully
regulated, numerous
variations
of basketball have developed for casual play. In some
countries, basketball is also a popular spectator sport.
While competitive basketball is primarily an indoor sport, played
on a
basketball court, less
regulated variations played in the outdoors have become
increasingly popular among both inner city and rural groups.
History
The first rules, court, and game
In early
December 1891, Dr. James Naismith, a
Canadian-born physical education professor
and instructor at the International Young Men's Christian
Association Training School (YMCA) (today, Springfield College) in Springfield,
Massachusetts
, USA, sought a vigorous indoor game to keep his
students occupied and at proper levels of fitness during the long
New
England
winters. After rejecting other ideas as
either too rough or poorly suited to walled-in
gymnasiums, he wrote the basic
rules and nailed a
peach basket onto a 10-foot (3.05 m) elevated
track. In contrast with modern basketball nets, this peach basket
retained its bottom, and balls had to be retrieved manually after
each "basket" or point scored; this proved inefficient, however, so
a hole was drilled into the bottom of the basket, allowing the
balls to be poked out with a long
dowel each
time. The peach baskets were used until 1906 when they were finally
replaced by metal hoops with backboards. A further change was soon
made, so the ball merely passed through, paving the way for the
game we know today. A
soccer ball was used to
shoot baskets. Whenever a person got the ball in the basket, his
team would gain a point. Whichever team got the most points won the
game. The baskets were originally nailed to the mezzanine balcony
of the playing court, but this proved impractical when spectators
on the balcony began to interfere with shots. The backboard was
introduced to prevent this interference; it had the additional
effect of allowing rebound shots.Naismith's handwritten diaries,
discovered by his granddaughter in early 2006, indicate that he was
nervous about the new game he had invented, which incorporated
rules from a children's game called "
Duck
on a Rock", as many had failed before it. Naismith called the
new game "Basket Ball".
The first official game was played in the YMCA gymnasium on January
20, 1892 with nine players. The game ended at 1-0; the shot was
made from , on a court just half the size of a present-day
Streetball or
National Basketball
Association (NBA) court. By 1897–1898 teams of five became
standard.
Women's basketball
Women's
basketball began in 1892 at Smith College
when Senda Berenson,
a physical education teacher, modified Naismith's rules for
women. Shortly after she was hired at Smith, she went to
Naismith to learn more about the game. Fascinated by the new sport
and the values it could teach, she organized the first women’s
collegiate basketball game on March 21, 1893, when her Smith
freshmen and sophomores played against one another. Her rules were
first published in 1899 and two years later Berenson became the
editor of
A.G. Spalding’s first Women's
Basketball Guide, which further spread her version of basketball
for women.
Surge in popularity
Basketball's early adherents were dispatched
to YMCAs throughout the United States
, and it quickly spread through the USA and Canada
. By
1895, it was well established at several women's high schools.
While the YMCA was responsible for initially developing and
spreading the game, within a decade it discouraged the new sport,
as rough play and rowdy crowds began to detract from the YMCA's
primary mission. However, other amateur sports clubs, colleges, and
professional clubs quickly filled the void. In the years before
World War I, the
Amateur Athletic Union and the
Intercollegiate
Athletic Association of the United States (forerunner of the
NCAA) vied
for control over the rules for the game. The first pro league, the
National Basketball League, was formed in 1898 to protect players
from exploitation and to promote a less rough game. This league
only lasted five years.
Basketball Hall of Fame founded
By the 1950s, basketball had become a major college sport, thus
paving the way for a growth of interest in professional basketball.
In 1959, a
basketball hall
of fame
was founded in Springfield,
Massachusetts
, site of the first game. Its rosters include
the names of great players, coaches, referees and people who have
contributed significantly to the development of the game. The hall
of fame has people who have accomplished mant goals in their career
in basketball.
Development of equipment and technique
Basketball was originally played with a
soccer ball. The first balls made
specifically for basketball were brown, and it was only in the late
1950s that
Tony Hinkle, searching for a
ball that would be more visible to players and spectators alike,
introduced the orange ball that is now in common use. Dribbling was
not part of the original game except for the "bounce pass" to
teammates. Passing the ball was the primary means of ball movement.
Dribbling was eventually introduced but limited by the asymmetric
shape of early balls. Dribbling only became a major part of the
game around the 1950s, as manufacturing improved the ball
shape.
Historical antecedents
Basketball,
netball,
dodgeball,
volleyball,
and
lacrosse are the only ball games which
have been identified as being invented by North Americans. Other
ball games, such as
baseball and
Canadian football, have
Commonwealth of Nations,
European,
Asian or
African connections. Although there is no direct
evidence as yet that the idea of basketball came from the ancient
Mesoamerican ballgame,
knowledge of that game had been available for at least 50 years
prior to Naismith's creation, in the writings of
John Lloyd Stephens and
Alexander von Humboldt. Stephens'
works especially, which included drawings by
Frederick Catherwood, were available at
most educational institutions in the 19th century and also had wide
popular circulations.
Early college basketball development
Dr. James Naismith was instrumental in establishing
college basketball.
He coached at the
University of
Kansas
for six years, before handing the reins to renowned
coach Forrest "Phog" Allen.
Naismith's
disciple Amos Alonzo Stagg brought
basketball to the University of Chicago
, while Adolph Rupp, a
student of Naismith's at Kansas, enjoyed great success as coach at
the University of
Kentucky
.
On
February 9, 1895, the first intercollegiate 5-on-5 game was played
at Hamline
University
between Hamline and the School of Agriculture,
which was affiliated with University of Minnesota
. The School of Agriculture won in a 9-3
game.
In 1901,
colleges, including the University of Chicago
, Columbia
University, Dartmouth
College
, the University of Minnesota
, the U.S.
Naval Academy
, the University of Utah
and Yale University
began sponsoring men's games. In 1905,
frequent injuries on the
football
field prompted
President Theodore Roosevelt to suggest that
colleges form a governing body, resulting in the creation of the
Intercollegiate Athletic Association of the United States (IAAUS).
In 1910, that body would change its name to the
National Collegiate
Athletic Association (
NCAA).
Early women's basketball development
In 1891, the
University of
California and Miss Head's School played the first women's
interinstitutional game.
Berenson's freshmen played the sophomore
class in the first women's intercollegiate basketball game at
Smith
College
, March 21, 1893. The same year,
Mount
Holyoke
and Sophie Newcomb College
(coached by Clara
Gregory Baer) women began playing basketball.
By 1895,
the game had spread to colleges across the country, including
Wellesley
, Vassar
, and
Bryn
Mawr
. The first intercollegiate women's game was
on April 4, 1896.
Stanford
women played Berkeley
, 9-on-9, ending in a 2-1 Stanford
victory.
Women's basketball development was more structured than that for
men in the early years. In 1905, the Executive Committee on Basket
Ball Rules (National Women's Basketball Committee) was created by
the
American
Physical Education Association. These rules called for six to
nine players per team and 11 officials. The
International Women's
Sports Federation (1924) included a women's basketball
competition. 37 women's high school varsity basketball or state
tournaments were held by 1925. And in 1926, the Amateur Athletic
Union backed the first
national women's
basketball championship, complete with men's rules.
The
Edmonton Grads, a touring Canadian
women's team based in Edmonton, Alberta
, operated between 1915 and 1940. The Grads
toured all over
North America, and
were exceptionally successful. They posted a record of 522 wins and
only 20 losses over that span, as they met any team which wanted to
challenge them, funding their tours from gate receipts. The Grads
also shone on several exhibition trips to
Europe, and won four consecutive exhibition
Olympics tournaments, in 1924, 1928, 1932, and
1936; however, women's basketball was not an official Olympic sport
until 1976. The Grads' players were unpaid, and had to remain
single. The Grads' style focused on team play, without overly
emphasizing skills of individual players.
The first women's
AAU
All-America team was chosen in 1929. Women's industrial leagues
sprang up throughout the United States, producing famous athletes,
including
Babe Didrikson of the
Golden Cyclones, and the
All American Red Heads Team,
which competed against men's teams, using men's rules. By 1938, the
women's national championship changed from a three-court game to
two-court game with six players per
team.
First Canadian interuniversity game
The first
Canadian interuniversity basketball game was played at the YMCA in Kingston, Ontario
on February 6, 1904, when McGill
University
visited Queen's University
. McGill won 9-7 in overtime; the score was
7-7 at the end of regulation play, and a ten-minute overtime period
settled the outcome. A good turnout of spectators watched the game.
Early American professional and barnstorming teams
Teams abounded throughout the 1920s. There were hundreds of men's
professional basketball
teams in towns and cities all over the United States, and little
organization of the professional game. Players jumped from team to
team and teams played in armories and smoky dance halls. Leagues
came and went. Barnstorming squads such as the
Original Celtics and two all-
African American teams, the
New York Renaissance Five ("Rens") and
(still in existence as of 2009) the
Harlem Globetrotters played up to two
hundred games a year on their national tours.
American national college championships
The first men's national championship tournament, the National
Association of Intercollegiate Basketball tournament, which still
exists as the
National
Association of Intercollegiate Athletics (NAIA)
tournament, was
organized in 1937. The first national championship for NCAA teams,
the
National Invitation
Tournament (NIT) in New York, was organized in 1938; the
NCAA
national tournament would begin one year later.
College basketball was rocked by gambling scandals from 1948 to
1951, when dozens of players from top teams were implicated in
match fixing and
point shaving. Partially spurred by an
association with cheating, the NIT lost support to the NCAA
tournament.
U.S. high school basketball
Before widespread school district consolidation, most United States
high schools were far smaller than their
present day counterparts. During the first decades of the 20th
century, basketball quickly became the ideal interscholastic sport
due to its modest equipment and personnel requirements. In the days
before widespread
television coverage of
professional and college sports, the popularity of high school
basketball was unrivaled in many parts of America. Perhaps the most
legendary of high school teams was Indiana's
Franklin Wonder Five, which took the
nation by storm during the 1920s, dominating Indiana basketball and
earning national recognition.
Today virtually every high school in the United States fields a
basketball team in
varsity competition.
Basketball's popularity remains high, both in rural areas where
they carry the identification of the entire community, as well as
at some larger schools known for their basketball teams where many
players go on to participate at higher levels of competition after
graduation. In the 2003–04 season, 1,002,797 boys and girls
represented their schools in interscholastic basketball
competition, according to the
National
Federation of State High School Associations.
The states of
Illinois
, Indiana
and Kentucky
are particularly well known for their residents'
devotion to high school basketball, commonly called Hoosier Hysteria in Indiana; the critically
acclaimed film Hoosiers shows high
school basketball's depth of meaning to these rural
communities.
National championships
There is currently no national tournament to determine a national
champion.
The most
serious effort was the National
Interscholastic Basketball Tournament at the University of
Chicago
from 1917 to 1930. The event organized by
Amos Alonzo Stagg and sent
invitations to state champion teams. The tournament started out as
a mostly Midwest affair but grew. In 1929 it had 29 state
champions. Faced with opposition from the
National
Federation of State High School Associations and
North Central
Association of Colleges and Schools that bore a threat of the
schools losing their accreditation the last tournament was in 1930.
The organizations said they were concerned that the tournament was
being used to recruit professional players from the prep
ranks.
The tournament did not invite minority schools or private/parochial
schools.
The
National Catholic Interscholastic Basketball Tournament ran from
1924 to 1941 at Loyola University
. The National Catholic Invitational
Basketball Tournament from 1954 to 1978 playing at a series of
venues at Catholic University
, Georgetown
and George Mason
.
The
National Interscholastic Basketball Tournament for Black High
Schools was held from 1929 to 1942 at Hampton Institute
. The National Invitational Interscholastic
Basketball Tournament was held from 1941 to 1967 starting out at
Tuskegee
Institute
. Following a pause during World War II it resumed at Tennessee
State College
in Nashville. The basis for the champion
dwindled after 1954 when
Brown v. Board of Education began an
integration of schools.
The last tournaments were held at Alabama
State College
from 1964 to 1967.
National Basketball Association
In 1946, the Basketball Association of America (BAA) was formed.
The first
game was played in Toronto
, Ontario, Canada between the Toronto Huskies and New York Knickerbockers on November 1,
1946. Three seasons later, in 1949, the BAA merged with the
National
Basketball League to form the
National Basketball
Association (
NBA). An upstart organization,
the
American Basketball
Association, emerged in 1967 and briefly threatened the NBA's
dominance until the
ABA-NBA merger in
1976. Today the NBA is the top professional basketball league in
the world in terms of popularity, salaries, talent, and level of
competition.
The NBA has featured many famous players, including
George Mikan, the first dominating "big man";
ball-handling wizard
Bob Cousy and
defensive genius
Bill Russell of the
Boston Celtics;
Wilt Chamberlain, who originally played for
the barnstorming
Harlem
Globetrotters; all-around stars
Oscar Robertson and
Jerry West; more recent big men
Kareem Abdul-Jabbar and
Karl Malone; playmaker
John Stockton; crowd-pleasing forward
Julius Erving; European stars
Dirk Nowitzki and
Dražen Petrović and the three
players who many credit with ushering the professional game to its
highest level of popularity:
Larry Bird,
Earvin "Magic" Johnson, and
Michael Jordan.
In 2001, the NBA formed a developmental league, the
NBDL. As of 2008, the league has
sixteen teams.
Women's National Basketball Association
The NBA-backed Women's National Basketball Association (WNBA) began
in 1997. Though it had shaky attendance figures, several marquee
players (
Lisa Leslie,
Diana Taurasi, and
Candace Parker among others) have helped the
league's popularity and level of competition. Other
professional women's basketball
leagues in the United States, such as the
American Basketball
League , have folded in part because of the popularity of the
WNBA.
The WNBA has been looked at by many as a niche league. However, the
league has recently taken steps forward.
In June 2007, the WNBA signed a contract extension with
ESPN. The new television deal runs from 2009 to 2016.
Along with this deal, came the first ever rights fees to be paid to
a women's professional sports league. Over the eight years of the
contract, "millions and millions of dollars" will be "dispersed to
the league's teams."
The WNBA gets more viewers on national television broadcasts
(413,000) than both
Major League
Soccer (253,000) and the
NHL
(310,732).
In a March 12, 2009 article,
NBA commissioner
David Stern said that in the bad
economy, "the NBA is far less profitable than the WNBA. We're
losing a lot of money amongst a large number of teams. We're
budgeting the WNBA to break even this year."
Philippine Basketball Association
The Philippine Basketball Association is the second oldest
professional league in the world.
The first game was played on April 9,
1975 at the Araneta
Coliseum
in Cubao, Quezon City
. Philippines
. It was founded as a "rebellion" of several
teams from the now-defunct Manila Industrial and Commercial
Athletic Association which was tightly controlled by the Basketball
Association of the Philippines (now defunct), the then-FIBA
recognized national association. Nine teams from the MICAA
participated in the league's first season that opened in April 9,
1975.
International basketball
The
International
Basketball Federation was formed in 1932 by eight founding
nations: Argentina
, Czechoslovakia
, Greece
, Italy
, Latvia
, Portugal
, Romania
and Switzerland
. At this time, the organization only oversaw
amateur players. Its acronym, derived from the French
Fédération Internationale de Basketball Amateur, was thus
"
FIBA."
Men's
Basketball was first included in the Berlin
Olympic Games in 1936, although a
demonstration tournament was held in 1904. The United States
defeated Canada in the first final, played outdoors.
This competition has
usually been dominated by the United States, whose team has won all
but three titles, the first loss in a controversial final game in
Munich
in 1972 against the
Soviet Union. In 1950 the first FIBA World Championship for men was
held in Argentina
. Three years later, the first FIBA World Championship for
Women was held in Chile
.
Women's
basketball was added to the Olympics in 1976, which were held in
Montreal
, Canada with teams such as the Soviet Union
, Brazil and Australia
rivaling the American
squads.
Pros in the Olympics
FIBA dropped the distinction between amateur and professional
players in 1989, and in 1992, professional players played for the
first time in the Olympic Games. The United States' dominance
continued with the introduction of their
Dream Team.
However, with developing programs elsewhere, other national teams
started to beat the United States.
A team made entirely of NBA players
finished sixth in the 2002 World Championships in Indianapolis
, behind Yugoslavia, Argentina, Germany, New Zealand and
Spain. In the
2004 Athens Olympics, the
United States suffered its first Olympic loss while using
professional players, falling to
Puerto Rico (in a
19-point loss) and
Lithuania in group games,
and being eliminated in the semifinals by
Argentina. It eventually
won the bronze medal defeating Lithuania, finishing behind
Argentina and
Italy.
In 2006, in the World Championship of Japan, the United States
advanced to the semifinals but were defeated by
Greece by 101-95. In the
bronze medal game it beat team
Argentina and finished
3rd behind Greece and Spain.
International stars in the NBA
Worldwide, basketball tournaments are held for boys and girls of
all age levels. The global popularity of the sport is reflected in
the nationalities represented in the NBA. Players from all over the
globe can be found in NBA teams:
- Chicago Bulls
star forward Luol Deng is a Sudanese
refugee who settled in Great Britain.
- Steve Nash, who won the 2005 and 2006
NBA MVP award, is a
South Africa–born Canadian.
- Andrea Bargnani of the Toronto Raptors, top pick in the 2006 NBA Draft, is from Italy. In addition,
American superstar Kobe Bryant spent
much of his childhood in Italy while his
father was playing there.
- Dallas Mavericks superstar and
2007 NBA MVP Dirk Nowitzki is
German.
- All-Star Pau Gasol of the Los Angeles Lakers is from Spain.
- 2005 NBA Draft top overall pick
Andrew Bogut of the Milwaukee Bucks is Australian. Also, 2008–09
rookie Nathan Jawai is the first
Indigenous Australian ever to
play in the league.
- Houston Rockets All-star center
Yao Ming is from China.
- All
star and former three point champion Peja Stojakovic is Serbian
.
- All star Andrei
Kirilenko is Russian.
- Phoenix Suns
guard Leandro Barbosa, Cleveland Cavaliers forward Anderson Varejao and Denver Nuggets center Nenê are Brazilian
.
- Cleveland
Cavaliers big man Žydrūnas Ilgauskas is Lithuanian
.
- Perhaps no NBA team is as identified by international players
as the San Antonio Spurs.
The
team's three most prominent players are all international—Tim
Duncan of the U.S.
Virgin Islands
, Manu Ginobili of
Argentina
and Tony Parker of
France (Duncan competes for the United States internationally, as
the Virgin Islands did not field a basketball team for
international competition until well after Duncan started playing
internationally, and all U.S. Virgin Islands natives are
United States citizens by birth).
- Ginobili's countryman Andrés
Nocioni plays for the Sacramento
Kings.
Even in the '90s, many non-American players made their names in the
NBA, such as Croats
Dražen
Petrović and
Toni Kukoč, Serb
Vlade Divac, Lithuanians
Arvydas Sabonis and
Šarūnas Marčiulionis and
German
Detlef Schrempf.
Globalization of basketball
The
all-tournament teams at the two most recent FIBA World Championships, held in
2002 in Indianapolis
and 2006 in Japan, demonstrate the
globalization of the game equally dramatically. Only one
member of either team was American, namely
Carmelo Anthony in 2006. The 2002 team
featured Nowitzki, Ginobili, Yao,
Peja Stojakovic of Yugoslavia (now
of
Serbia), and
Pero Cameron of New Zealand. Ginobili
also made the 2006 team; the other members were Anthony, Gasol, his
Spanish teammate
Jorge Garbajosa and
Theodoros Papaloukas of
Greece. The only players on
either team to never have joined the NBA are Cameron and
Papaloukas. The strength of international Basketball is evident in
the fact that the last three FIBA world championships were won (in
order) by Serbia (Yugoslavia in 1998) and Spain.
Rules and regulations
Measurements and time limits discussed in this section often vary
among tournaments and organizations; international and NBA rules
are used in this section.
The object of the game is to outscore one's opponents by throwing
the ball through the opponents' basket from above while preventing
the opponents from doing so on their own. An attempt to score in
this way is called a
shot. A successful shot is
worth two points, or
three
points if it is taken from beyond the three-point arc which is
from the basket in international games and in NBA games.
Playing regulations
Games are played in four quarters of 10 (international) or 12
minutes (NBA). College games use two 20-minute halves, while high
school games use 8 minute quarters. Fifteen minutes are allowed for
a half-time break, and two minutes are allowed at the other breaks.
Overtime periods are
five minutes long. Teams exchange baskets for the second half. The
time allowed is actual playing time; the clock is stopped while the
play is not active. Therefore, games generally take much longer to
complete than the allotted game time, typically about two
hours.
Five players from each team (out of a twelve player roster) may be
on the court at one time.
Substitutions
are unlimited but can only be done when play is stopped. Teams also
have a
coach, who oversees the
development and strategies of the team, and other team personnel
such as assistant coaches, managers, statisticians, doctors and
trainers.
For both men's and women's teams, a standard uniform consists of a
pair of shorts and a
jersey with a
clearly visible number, unique within the team, printed on both the
front and back. Players wear
high-top
sneakers that provide extra ankle support. Typically, team names,
players' names and, outside of North America, sponsors are printed
on the uniforms.
A limited number of time-outs, clock stoppages requested by a coach
(or sometimes mandated in the NBA) for a short meeting with the
players, are allowed. They generally last no longer than one minute
(140 seconds in the NBA) unless, for televised games, a commercial
break is needed.
The game is controlled by the officials consisting of the referee
(referred to as crew chief in the NBA), one or two umpires
(referred to as referees in the NBA) and the table officials. For
college, the NBA, and many high schools, there are a total of three
referees on the court. The table officials are responsible for
keeping track of each teams scoring, timekeeping, individual and
team
fouls, player
substitutions, team
possession
arrow, and the
shot clock.
Equipment
The only essential equipment in a basketball game is the basketball
and the court: a flat, rectangular surface with baskets at opposite
ends (or in the case of 3-on-3 street basketball, half a court with
one basket). Competitive levels require the use of more equipment
such as clocks, scoresheets, scoreboard(s), alternating possession
arrows, and whistle-operated stop-clock systems.
An outdoor basketball net.
A regulation
basketball court in
international games is 28 by 15 meters (approx. 92 by 49 ft)
and in the NBA is 94 by 50 feet (29 by 15 m). Most courts are made
of wood, usually maple. A steel basket with net and backboard hang
over each end of the court. At almost all levels of competition,
the top of the rim is exactly above the court and inside the
baseline. While variation is possible in the dimensions of the
court and backboard, it is considered important for the basket to
be of the correct height; a rim that is off by but a few inches can
have an adverse effect on shooting.
There are also regulations on the size a basketball should be. If
women are playing, the official basketball size is 28.5" in
circumference (size 6, or a "285 ball") and a weight of 20 oz. For
men, the official ball is 29.5" in circumference (size 7, or a "295
ball") and weighs 22 oz.
Violations
The ball may be advanced toward the basket by being shot, passed
between players, thrown, tapped, rolled or dribbled (bouncing the
ball while running).
The ball must stay within the court; the last team to touch the
ball before it travels out of bounds forfeits possession. The ball
is out of bounds if touches or crosses over a boundary line, or
touches a player who is out of bounds. This is in contrast to other
sports such as
soccer,
volleyball, and
tennis (but
not
rugby or
American football) where the ball (or
player) is still considered in if any part of it is touching a
boundary line.
The ball-handler may not move both feet without dribbling, an
infraction known as
traveling, nor may he dribble with
both hands or catch the ball in between dribbles, a violation
called
double dribbling. A player's
hand cannot be under the ball while dribbling; doing so is known as
carrying the ball. A team,
once having established ball control in the front half of the
court, may not return the ball to the backcourt and be the first to
touch it. The ball may not be kicked, nor be struck with the fist.
A violation of these rules results in loss of possession, or, if
committed by the defense, a reset of the
shot
clock (with some exceptions in the NBA).
There are limits imposed on the time taken before progressing the
ball past halfway (8 seconds in international and NBA; 10 seconds
in NCAA and high school), before attempting a shot (24 seconds in
the NBA, 30 seconds in NCAA women's and
Canadian Interuniversity
Sport play for both sexes, and 35 seconds in NCAA men's play),
holding the ball while closely guarded (5 seconds), and remaining
in the restricted area below the foul line (the lane, or "
key") (3 seconds). These rules are designed
to promote more offense.
No player may touch the ball on its downward flight to the basket,
unless the ball has no chance of entering the basket (goaltending).
In addition, no player may touch the ball while it is on or in the
basket; when any part of the ball is in the cylinder above the
basket (the area extended upwards from the basket); or when the
ball is outside the cylinder, if the player reaches through the
basket and touches it. This violation is known as "basket
interference". If a defensive player goaltends or commits basket
interference, the basket is awarded and the offending team gets the
ball. If a teammate of the shooter goaltends or commits
interference, the basket is cancelled and play continues with the
defensive team being given possession.
Fouls

The referee signals that a foul has
been committed.
An attempt to unfairly disadvantage an opponent through physical
contact is illegal and is called a foul. These are most commonly
committed by defensive players; however, they can be committed by
offensive players as well. Players who are fouled either receive
the ball to pass inbounds again, or receive one or more
free throws if they are fouled in the act of
shooting, depending on whether the shot was successful. One point
is awarded for making a free throw, which is attempted from a line
from the basket.
The referee may use discretion in calling fouls (for example, by
considering whether an unfair advantage was gained), sometimes
making fouls controversial calls or no-calls. The calling of fouls
can vary between games, leagues and even between referees.
A player or coach who shows poor sportsmanship, such as by arguing
with a referee or by fighting with another player, can be charged
with a more serious foul called a
technical foul. The penalty involves free
throws (where, unlike a personal foul, the other team can choose
any player to shoot) and varies between leagues. Repeated incidents
can result in
disqualification.
Blatant fouls with excessive contact or that are not an attempt to
play the ball are called intentional fouls (or flagrant fouls in
the NBA). In FIBA, a foul resulting in ejection is called a
disqualifying foul, while in leagues other than the NBA, such a
foul is referred to as flagrant.
If a team exceeds a certain limit of team fouls in a given period
(quarter or half) – four for NBA and international games – the
opposing team is awarded one or two free throws on all subsequent
non-shooting fouls for that period, the number depending on the
league. In the US college and high school games, if a team reaches
7 fouls in a half, the opposing team is awarded one free throw,
along with a second shot if the first is made. This is called
shooting "one-and-one". If a team exceeds 10 fouls in the half, the
opposing team is awarded two free throws on all subsequent fouls
for the half.
When a team shoots foul shots, the opponents may not interfere with
the shooter, nor may they try to regain possession until the last
or potentially last free throw is in the air.
After a team has committed a specified number of fouls, it is said
to be "in the penalty". On scoreboards, this is usually signified
with an indicator light reading "Bonus" or "Penalty" with an
illuminated directional arrow indicating that team is to receive
free throws when fouled by the opposing team. (Some scoreboards
also indicate the number of fouls committed.)
If a team misses the first shot of a two-shot situation, the
opposing team must wait for the completion of the second shot
before attempting to reclaim possession of the ball and continuing
play.
If a player is fouled while attempting a shot and the shot is
unsuccessful, the player is awarded a number of free throws equal
to the value of the attempted shot. A player fouled while
attempting a regular two-point shot, then, receives two shots. A
player fouled while attempting a three-point shot, on the other
hand, receives three shots.
If a player is fouled while attempting a shot and the shot is
successful, typically the playerwill be awarded one additional free
throw for one point. In combination with a regularshot, this is
called a "three-point play" or "four-point play" (or more
colloquially, an "and one") because of the basket made at the time
of the foul (2 or 3 points) and the additional free throw (1
point).
Common techniques and practices
Positions and structures

Basketball positions in the offensive
zone
Although the rules do not specify any
positions whatsoever, they have evolved
as part of basketball. During the first five decades of
basketball's evolution, one guard, two forwards, and two centers or
two guards, two forwards, and one center were used. Since the
1980s, more specific positions have evolved, namely:
- point guard: usually the fastest
player on the team, organizes the team's offense by controlling the
ball and making sure that it gets to the right player at the right
time
- shooting guard: creates a high
volume of shots on offense; guards the opponent's best perimeter
player on defense
- small forward: often primarily
responsible for scoring points via cuts to the basket and dribble
penetration; on defense seeks rebounds and steals, but sometimes
plays more actively
- power forward: plays
offensively often with his back to the basket; on defense, plays
under the basket (in a zone defense) or against the opposing power
forward (in man-to-man defense)
- center: uses height and size
to score (on offense), to protect the basket closely (on defense),
or to rebound.
The above descriptions are flexible. On some occasions, teams will
choose to use a
three guard offense, replacing one of the
forwards or the center with a third guard. The most commonly
interchanged positions are point guard and shooting guard,
especially if both players have good leadership and ball handling
skills.
There are two main defensive strategies:
zone defense and
man-to-man defense.
Zone
defense involves players in defensive positions guarding
whichever opponent is in their zone. In
man-to-man defense, each defensive player
guards a specific opponent and tries to prevent him from taking
action.
Offensive plays are more varied, normally involving planned passes
and movement by players without the ball. A quick movement by an
offensive player without the ball to gain an advantageous position
is a
cut. A legal attempt by an offensive player to stop
an opponent from guarding a teammate, by standing in the defender's
way such that the teammate cuts next to him, is a
screen
or
pick. The two plays are combined in the
pick and roll, in which a player sets a
pick and then "rolls" away from the pick towards the basket.
Screens and cuts are very important in offensive plays; these allow
the quick passes and teamwork which can lead to a successful
basket. Teams almost always have several offensive plays planned to
ensure their movement is not predictable. On court, the point guard
is usually responsible for indicating which play will occur.
Defensive and offensive structures, and positions, are more
emphasized in higher levels in basketball; it is these that a coach
normally requests a time-out to discuss.
Shooting

Player releases a short jump shot,
while her defender is either knocked down, or trying to "take a
charge."
Shooting is the act of attempting to score points by throwing the
ball through the basket. While methods can vary with players and
situations, the most common technique is outlined as follows:
The player faces the basket with feet about shoulder-width apart,
knees slightly bent, and back straight. The player allows the ball
to rest on the fingertips of the dominant hand (the shooting arm)
slightly above the head, with the other hand supporting the side of
the ball. To aim the ball, the player's elbow should be aligned
vertically, with the forearm facing in the direction of the basket.
The ball is shot by extending the bended knees and straightening
the shooting arm; the ball rolls off the finger tips while the
wrist completes a full downward flex motion. The shooting arm,
fully extended with the wrist fully bent, and the fingers pointing
downward, is held stationary for a moment following the release of
the ball, this is known as a follow-through, which when properly
done, enhances the accuracy of the shot. Generally, the
non-shooting arm is used only to guide the shot, not to power
it.
Players often try to put a steady backspin on the ball to deaden
its impact with the rim. The ideal trajectory of the shot is
somewhat arguable, but generally coaches recommends a proper arch.
Players may shoot directly into the basket or may use the backboard
to redirect the ball into the basket.
The two most common shots that use the above described set up are
the
set shot and the
jump shot. The set shot is taken
from a standing position, with neither foot leaving the floor,
typically used for free throws. The jump shot is taken while in
mid-air, when the ball is released near the top of the jump. This
provides much greater power and range, and it also allows the
player to elevate over the defender. Failure to release the ball
before the feet return to the ground is considered a traveling
violation.
Another common shot is called the
layup. This shot requires the player to be in
motion toward the basket, and to "lay" the ball "up" and into the
basket, typically off the backboard (the backboard-free, underhand
version is called a
finger roll). The most crowd-pleasing,
and typically highest-percentage accuracy shot is the
slam dunk, in which the player jumps very
high, and throws the ball downward, straight through the
hoop.
Another shot that is becoming common is the "circus shot". The
circus shot is a low-percentage shot that is flipped, heaved,
scooped, or flung toward the hoop while the shooter is off-balance,
airborne, falling down, and/or facing away from the basket.
A shot that misses both the rim and the backboard completely is
referred to as an
air ball. A particularly
bad shot, or one that only hits the backboard, is jocularly called
a
brick.
Rebounding
The objective of rebounding is to successfully gain possession of
the basketball after a missed field goal or free throw, as it
rebounds from the hoop or backboard. This plays a major role in the
game, as most possessions end when a team misses a shot. There are
two categories of rebounds: offensive rebounds, in which the ball
is recovered by the offensive side and does not change possession,
and defensive rebounds, in which the defending team gains
possession of the loose ball. The majority of rebounds are
defensive, as the team on defense tends to be in better position to
recover missed shots.
Passing
A pass is a method of moving the ball between players. Most passes
are accompanied by a step forward to increase power and are
followed through with the hands to ensure accuracy.
A staple pass is the
chest pass. The ball is passed
directly from the passer's chest to the receiver's chest. A proper
chest pass involves an outward snap of the thumbs to add velocity
and leaves the defence little time to react.
Another type of pass is the
bounce pass. Here, the passer
bounces the ball crisply about two-thirds of the way from his own
chest to the receiver. The ball strikes the court and bounces up
toward the receiver. The bounce pass takes longer to complete than
the chest pass, but it is also harder for the opposing team to
intercept (kicking the ball deliberately is a violation). Thus,
players often use the bounce pass in crowded moments, or to pass
around a defender.
The
overhead pass is used to pass the ball over a
defender. The ball is released while over the passer's head.
The
outlet pass occurs after a team gets a defensive
rebound. The next pass after the rebound is the
outlet
pass.
The crucial aspect of any good pass is it being difficult to
intercept. Good passers can pass the ball with great accuracy and
they know exactly where each of their other teammates prefers to
receive the ball. A special way of doing this is passing the ball
without looking at the receiving teammate. This is called a
no-look pass.
Another advanced style of passing is the
behind-the-back
pass which, as the description implies, involves throwing the
ball behind the passer's back to a teammate. Although some players
can perform such a pass effectively, many coaches discourage
no-look or behind-the-back passes, believing them to be difficult
to control and more likely to result in turnovers or
violations.
Dribbling
Dribbling is the act of bouncing the ball continuously with one
hand, and is a requirement for a player to take steps with the
ball. To dribble, a player pushes the ball down towards the ground
with the fingertips rather than patting it; this ensures greater
control.
When dribbling past an opponent, the dribbler should dribble with
the hand farthest from the opponent, making it more difficult for
the defensive player to get to the ball. It is therefore important
for a player to be able to dribble competently with both
hands.
Good dribblers (or "ball handlers") tend to bounce the ball low to
the ground, reducing the distance of travel of the ball from the
floor to the hand, making it more difficult for the defender to
"steal" the ball. Good ball handlers frequently dribble behind
their backs, between their legs, and switch directions suddenly,
making a less predictable dribbling pattern that is more difficult
to defend against. This is called a crossover, which is the most
effective way to move past defenders while dribbling.
A skilled player can dribble without watching the ball, using the
dribbling motion or
peripheral
vision to keep track of the ball's location. By not having to
focus on the ball, a player can look for teammates or scoring
opportunities, as well as avoid the danger of having someone steal
the ball away from him/her.
Blocking
A block is performed when, after a shot is attempted, a defender
succeeds in altering the shot by touching the ball. In almost all
variants of play, it is illegal to touch the ball after it is in
the downward path of its arc; this is known as
goaltending. It is also illegal under NBA
and Men's NCAA basketball, to block a shot after it has touched the
backboard, or when any part of the ball is directly above the
rim.
To block a shot, a player has to be able to reach a point higher
than where the shot is released. Thus, height can be an advantage
in blocking. Players who are taller and playing the power forward
or center positions generally record more blocks than players who
are shorter and playing the guard positions. However, with good
timing and a sufficiently high vertical leap, even shorter players
can be effective shot blockers.
Height
At the professional level, most male players are above and most
women above . Guards, for whom physical coordination and
ball-handling skills are crucial, tend to be the smallest players.
Almost all forwards in the men's pro leagues are or taller. Most
centers are over tall. According to a survey given to all NBA
teams, the average height of all NBA players is just under , with
the average weight being close to . The tallest players ever in the
NBA were
Manute Bol and
Gheorghe Mureşan, who were both tall.
The tallest current NBA player is
Yao Ming,
who stands at .
The shortest player ever to play in the NBA is
Muggsy Bogues at . Other short players have
thrived at the pro level.
Anthony "Spud"
Webb was just tall, but had a 42-inch (1.07 m) vertical leap,
giving him significant height when jumping. The shortest player in
the NBA as of the 2006-07 season is
Earl
Boykins at 5 feet 5 inches (1.65 m). While shorter players
are often not very good at defending against shooting, their
ability to navigate quickly through crowded areas of the court and
steal the ball by reaching low are strengths.
Variations and similar games
Variations of basketball are activities based on
the game of basketball, using common basketball skills and
equipment (primarily the ball and basket). Some variations are only
superficial rules changes, while others are distinct games with
varying degrees of basketball influences. Other variations include
children's games, contests or activities meant to help players
reinforce skills.
There are principal basketball sports with variations on basketball
including
Wheelchair
basketball,
Water
basketball,
Beach
basketball,
Slamball,
Streetball and
Unicycle basketball. An earlier
version of basketball was
Six-on-six basketball played
until the end of the 1950s.
Horseball is a game played on
horseback where a ball is handled and points are
scored by shooting it through a high net (approximately 1.5m×1.5m).
The sport is like a combination of
polo,
rugby, and basketball. There is even
a form played on donkeys known as
Donkey basketball, but that
version has come under attack from animal rights groups.
Games using basketball skills and equipment include popular
versions of the half-court game played in informal settings without
referees or strict rules. Perhaps the single most common variation
is the
half court game. Only one basket is used, and the
ball must be "cleared" - passed or dribbled outside the half-court
or three-point line -each time possession of the ball changes from
one team to the other. Half-court games require less
cardiovascular stamina, since players need
not run back and forth a full court. Half-court games also raise
the number of players that can use a court, an important benefit
when many players want to play. (Interestingly, half court games
are also played when there is an insufficient number of players to
form full 5-on-5 teams).
There are also other basketball sports like
Wheelchair Basketball
Wheelchair basketball, created by disabled
World War II veterans, is played on specially
designed wheelchairs for the physically impaired. The world
governing body of wheelchair basketball is the
International
Wheelchair Basketball Federation (IWBF).
Water Basketball
Water basketball, played in a swimming pool, merges basketball and
water polo rules.
Beach Basketball
A modified version of basketball, played on beaches, was invented
by Philip Bryant. Beach basketball is played in a circular court
with no backboard on the goal, no out-of-bounds rule with the ball
movement to be done via passes or 2½ steps, as dribbling is next to
impossible on a soft surface.Beach basketball has grown to a very
popular, widespread competitive sport. Fifteen Annual World
Championships have been organized.
Dunk Hoops
Dunk Hoops (aka Dunk Ball) is a variation of the game of
basketball, played on basketball hoops with lowered (under
basketball regulation 10 feet) rims. It originated when the
popularity of the slam dunk grew and was developed to create better
chances for dunks with lowered rims and using altered
goaltending rules.
Slamball
Slamball is full-contact basketball, with
trampolines. Points are scored by playing the
ball through the net, as in basketball, though the point-scoring
rules are modified. The main differences from the parent sport is
the court; below the padded basketball rim and
backboard are four trampolines set
into the floor which serve to propel players to great heights for
slam dunks. The rules also permit some
physical contact between the members of the four-player
teams.
Streetball
Streetball is a less formal variant of basketball, played on
playgrounds and in
gymnasiums across the world. Often only one half of the
court is used, but otherwise the rules of the game are very similar
to those of basketball. The number of participants in a game, or a
run, may range from one defender and one person on offense
(known as
one on one) to two full teams of five
each.
Streetball is a very popular game worldwide, and some cities in the
United States have organized streetball programs, such as
midnight basketball. Many cities also
host their own weekend-long streetball tournaments.
Unicycle Basketball
Unicycle basketball is played using a regulation basketball on a
regular basketball court with the same rules, e.g., one must
dribble the ball whilst riding. There are a number of rules that
are particular to unicycle basketball as well, e.g., a player must
have at least one foot on a pedal when in-bounding the ball.
Unicycle basketball is usually played using 24" or smaller
unicycles, and using plastic pedals, both to preserve the court and
the players' shins. In North America, popular unicycle basketball
games are organized..
More distantly related basketball games
Spin-offs from basketball that are now separate sports include:
- Korfball (Dutch:
Korfbal) started in the Netherlands and is now played worldwide as
a mixed gender team ball game, similar to mixed netball and
basketball
- Netball (formerly known
as Women basketball but now played by both males and females), a
limited-contact team sport in which two teams of seven try to score
points against one another by placing a ball through a high
hoop,
- Slamball, a
full-contact basketball, with trampolines. Points are scored by
playing the ball through the net, as in basketball, though the
point-scoring rules are modified. The main differences from the
parent sport is the court; below the padded basketball rim and
backboard are four trampolines set into the floor which serve to
propel players to great heights for slam dunks. The rules also
permit some physical contact between the members of the four-player
teams.
Social forms of basketball
Basketball has been adopted by various social groups and for which
they have established their own environments and sometimes their
own rules. Such socialized forms of basketball include:
- Recreational basketball, where fun,
entertainment and family and camaraderie rule rather than winning a
game
- Basketball Schools and Academies where
students are trained in developing basketball fundamentals, undergo
fitness and endurance exercises and learn various basketball
skills. Basketball students learn proper ways of passing, ball
handling, dribbling, shooting from various distances, rebounding,
offensive moves, defense, lay-ups, screens etc, basketball rules
and basketball ethics. Also popular are the basketball
camps organized at various occasions, often to get
prepared for basketball events and basketball
clinics for improving skills.
- College and University basketball played in
educational institutions of higher learning
- Disabled basketball played by various disabled
groups such as:
- Ethnic and Religion-based basketball. Examples
of Ethnic basketball include Indo-Pak or Russian or Armenian
leagues in the United States or Canada for example or Filipino
expatriate basketball leagues in the Gulf or the United States.
Whereas Relegion-based basketball includes most notably
church-related Christian basketball leagues, Jewish, Muslim and
Hindu basketball leagues etc. or denominational leagues like
Coptic, Syriac/Assyrian basketball leagues in the United States or
Canada.
- Gay basketball played in gay, lesbian, bisexual and transgender communities in gay basketball
leagues. Sport of basketball is a major part of events during the
Gay Games, World
Outgames and EuroGames.
- Midnight
basketball, a basketball initiative to curb inner-city
crime in the United States and elsewhere by keeping urban youth off
the streets and engaging them with sports alternatives to drugs and
crime.
- Mini basketball played by underage
children
- Maxi Basketball played by overage
individuals
- Prison basketball, basketball practiced in
prisons and penitentiary institutions. There
are also active religious basketball missionary groups to play
basketball with prisoners. Some prisons have developed their prison
basketball leagues. At times, non-prisoners may play in such
leagues, provided all home and away games are played within prison
courts. Film director Jason Moriarty
has even released a documentary relating to the sport entitled
Prison Ball.
- Rezball, short for
reservation ball, is the term used to describe the avid Native American
following of basketball and in some areas the style of play of
their Native American teams.
- School / High school basketball, the sport of
basketball being one of the most frequently exercised and popular
sports in all school systems
- Show basketball as performed by entertainment
basketball show teams, the prime example being the Harlem Globetrotters. There are even
specialized entertainment teams like:
- Celebrity basketball teams made of celebrities
(actors, singers etc) playing in their own leagues or in public,
often for entertainment and charity events.
- Midget basketball teams made up of athletes of
short stature offering shows using
basketball
- Slamball offered as
entertainment events
- Women
basketball played by females
Fantasy basketball
Fantasy basketball was inspired by
fantasy baseball. Originally played by
keeping track of stats by hand, it was popularized during the 1990s
after the advent of the Internet. Those who play this game are
sometimes referred to as General Managers, who draft actual
NBA players and
compute their
basketball
statistics. The game was popularized by
ESPN Fantasy Sports,
NBA.com,
and
Yahoo! Fantasy Sports. Other sports
websites provided the same format keeping the game interesting with
participants actually owning specific players.
