The rules of basketball are the rules and regulations that govern the play, officiating, equipment and procedures of basketball. While many of the basic rules are uniform throughout the world, variations do exist. Most leagues or governing bodies in North America, the most important of which are the National Basketball Association and NCAA, formulate their own rules. In addition, the Technical Commission of the International Basketball Federation (FIBA) determines rules for international play; most leagues outside North America use the complete FIBA ruleset.
On January 15, 1892, James Naismith published his rules for the game of "Basket Ball" that he invented:The original game played under these rules was quite different from the one played today as there was no dribbling, dunking, three-pointers, or shot clock, and goal tending was legal.
Naismith's original 1892 manuscript of the rules of basketball, one of the most expensive manuscripts in existence, is publicly displayed at the University of Kansas.
Naismith's original rules did not specify how many players were to be on the court. In 1900, five players became standard, and players that were substituted were not allowed to re-enter the game.[ citation needed ] Players were allowed to re-enter a game once from 1921, and twice from 1934; such restrictions on substitutions were abolished in 1945 when substitutions became unlimited. Coaching was originally prohibited during the game, but from 1949, coaches were allowed to address players during a time-out.
Originally a player was disqualified on his second foul. This limit became four fouls in 1911 and five fouls in 1945, still the case in most forms of basketball where the normal length of the game (before any overtime periods) is 40 minutes. When the normal length is 48 minutes (this is the case with the National Basketball Association in the United States and Canada) a player is accordingly disqualified on his sixth foul.
The first time restriction on possession of the ball was introduced in 1933, where teams were required to advance the ball over the center line within ten seconds of gaining possession. This rule remained until 2000, when FIBA reduced the requirement to eight seconds, the NBA following suit in 2001. The NCAA retains the 10-second rule for men's play, and adopted this rule for women's play starting with the 2013–14 season.U.S. high schools, whose rules are drafted by NFHS, also use the 10-second rule for both sexes.
In 1936 the three-second rule was introduced. This rule prohibits offensive players from remaining near their opponents' basket for longer than three seconds (the precise restricted area is also known as the lane or the key ). A game central to this rule's introduction was that between the University of Kentucky and New York University. Kentucky coach Adolph Rupp did not take one of his referees with him, despite being warned of discrepancies in officiating between the Midwest and East by Notre Dame coach George Keogan, and the game became especially rough. Because of this game and others, 6 ft 5 in (1.96 m) Kentucky All-American center Leroy Edwards is generally recognized as the player responsible for the three-second rule.
While the rule was originally adopted to reduce roughness in the area between big men, it is now considered to prevent tall offensive players from gaining an advantage by waiting close to the basket. When the NBA started to allow zone defense in 2001, a three-second rule for defensive players was also introduced.
The shot clock was first introduced by the NBA in 1954, to increase the speed of play. Teams were then required to attempt a shot within 24 seconds of gaining possession, and the shot clock would be reset when the ball touched the basket's rim or the backboard, or the opponents gained possession. FIBA adopted a 30-second shot clock two years later, resetting the clock when a shot was attempted. Women's basketball adopted a 30-second clock in 1971. The NCAA adopted a 45-second shot clock for men while continuing with the 30-second clock for women in 1985. The men's shot clock was then reduced to 35 seconds in 1993, and further reduced to 30 seconds in 2015. FIBA reduced the shot clock to 24 seconds in 2000, and changed the clock's resetting to when the ball touched the rim of the basket. Originally, a missed shot where the shot clock expired while the ball is in the air constituted a violation. In 2003 the rule was changed so that the ball remains live in this situation, as long as it touched the rim. If the ball touches the rim and slightly bounces over the basketball hoop it will be called as a loose ball.
Dribbling was not part of the original game, but was introduced in 1901. At the time, a player could only bounce the ball once, and could not shoot after he had dribbled. The definition of dribbling became the "continuous passage of the ball" in 1909, allowing more than one bounce, and a player who had dribbled was then allowed to shoot.
Running with the ball ceased to be considered a foul in 1922, and became a violation, meaning that the only penalty was loss of possession. Striking the ball with the fist has also become a violation. From 1931, if a closely guarded player withheld the ball from play for five seconds, play was stopped and resumed with a jump ball; such a situation has since become a violation by the ball-carrier. Goaltending became a violation in 1944, and offensive goaltending in 1958.
Free throws were introduced shortly after basketball was invented. In 1895, the free throw line was officially placed fifteen feet (4.6 m) from the backboard, prior to which most gymnasiums placed one twenty feet (6.1 m) from the backboard. From 1924, players that received a foul were required to shoot their own free throws. One free throw shot is awarded to a player who was fouled while making a successful field goal attempt. If the field goal attempt is unsuccessful, two free throw shots are awarded (three if the player was attempting a three-point field goal). If an offensive player is fouled while not in the act of shooting, or if a player is fouled in a loose-ball situation, the penalty varies by level of play and the number of fouls accumulated by the opposing team in a given period.
A player has 10 seconds to attempt a free throw. If the player does not attempt a free throw within 10 seconds of receiving the ball, the free throw attempt is lost, and a free throw violation is called. A free throw violation also occurs if a free throw misses the backboard, rim, and basket. If a free throw violation is assessed on the last free throw awarded to a player in a given situation, possession automatically reverts to the opposing team.
A charge is physical contact between an offensive player and a defensive player. In order to draw an offensive charge the defensive player must establish legal guarding positioning in the path of the offensive player. If contact is made, the officials would issue an offensive charge. No points will be allowed and the ball is turned over. The defensive player may not draw an offensive charge in the "restricted zone" (see below for more details).
Blocking is physical contact between the offensive player and the defensive player. Blocking fouls are issued when a defensive player interferes with the path of the offensive player in the shooting motion. Blocking fouls are easily called when the defensive player is standing in the "restricted zone".
Restricted zone: In 1997, the NBA introduced an arc of a 4-foot (1.2 m) radius around the basket, in which an offensive foul for charging could not be assessed. This was to prevent defensive players from attempting to draw an offensive foul on their opponents by standing underneath the basket. FIBA adopted this arc with a 1.25-meter (4 ft 1 in) radius in 2010.
The ball was to be an "ordinary Association football". In other words, a soccer ball. 10 feet (3.05 m) above the court. Originally a basket was used (thus "basket-ball"), so the ball had to be retrieved after each made shot. Today a hoop with an open-bottom hanging net is used instead.The goal is placed
Originally, there was one umpire to judge fouls and one referee to judge the ball; the tradition of calling one official the "referee" and the other one or two the "umpires" has remained (the NBA, however, uses different terminology, referring to the lead official as "crew chief" and the others as "referees"). Today, both classes of officials have equal rights to control all aspects of the game. The NBA added a third official in 1988, and FIBA did so afterward, using it for the first time in international competition in 2006. The use of video evidence to inform referee's decisions has always been banned, except in the case of determining whether or not the last shot of a period was attempted before time expired. This exception was introduced by the NBA in 2002 and adopted by FIBA in 2006. The NCAA, however, has permitted instant replay for timing, the value of a field goal (two or three points), shot clock violations, and for purposes of disqualifying players because of unsportsmanlike conduct. The NBA changed its rules starting in 2007 to allow officials the ability to view instant replay with plays involving flagrant fouls, similar to the NCAA. In Italy's Serie A, an American football-style coach's challenge is permitted to challenge (at the next dead ball) an official's call on any situation similar to the NCAA.
The center jump ball that was used to restart a game after every successful field goal was eliminated in 1938, in favor of the ball being given to the non-scoring team from behind the end line where the goal was scored, in order to make play more continuous. The jump ball was still used to start the game and every period, and to restart the game after a held ball. However, the NBA stopped using the jump ball to start the second through fourth quarters in 1975, instead using a quarter-possession system where the loser of the jump ball takes the ball from the other end to start the second and third periods, while the winner of that jump ball takes the ball to start the fourth period from the other end of the court.
In 1981, the NCAA adopted the alternating possession system for all jump ball situations except the beginning of the game, and in 2003, FIBA adopted a similar rule, except for the start of the third period and overtime. In 2004, the rule was changed in FIBA that the arrow applies for all situations after the opening tap.
In 1976, the NBA introduced a rule to allow teams to advance the ball to the center line following any legal time-out in the final two minutes of the game. FIBA followed suit in 2006.
The most recent international rules of basketball were approved February 2, 2014 by FIBA and became effective October 1 of that year.
There are eight rules encompassing 50 articles, covering equipment and facilities, regulations regarding teams, players, captains and coaches, playing regulations, violations, fouls and their penalties, special situations, and the officials and table officials. The rules also cover officials' signals, the scoresheet, protest procedure, classification of teams and television timeouts.
Basketball, colloquially referred to as hoops, is a team sport in which two teams, most commonly of five players each, opposing one another on a rectangular court, compete with the primary objective of shooting a basketball through the defender's hoop while preventing the opposing team from shooting through their own hoop. A field goal is worth two points, unless made from behind the three-point line, when it is worth three. After a foul, timed play stops and the player fouled or designated to shoot a technical foul is given one, two or three one-point free throws. The team with the most points at the end of the game wins, but if regulation play expires with the score tied, an additional period of play (overtime) is mandated.
In basketball, the basketball court is the playing surface, consisting of a rectangular floor, with baskets at each end. In professional or organized basketball, especially when played indoors, it is usually made out of a wood, often maple, and highly polished and completed with a 10 foot rim. Outdoor surfaces are generally made from standard paving materials such as concrete or asphalt.
College basketball in the United States is governed by collegiate athletic bodies including National Collegiate Athletic Association (NCAA), the National Association of Intercollegiate Athletics (NAIA), the United States Collegiate Athletic Association (USCAA), the National Junior College Athletic Association (NJCAA), and the National Christian College Athletic Association (NCCAA). Each of these various organizations are subdivided into from one to three divisions based on the number and level of scholarships that may be provided to the athletes.
In basketball, a technical foul is any infraction of the rules penalized as a foul which does not involve physical contact during the course of play between opposing players on the court, or is a foul by a non-player. The most common technical foul is for unsportsmanlike conduct. Technical fouls can be assessed against players, bench personnel, the entire team, or even the crowd. These fouls, and their penalties, are more serious than a personal foul, but not necessarily as serious as a flagrant foul.
A shot clock is a countdown timer used in basketball that provides a set amount of time that a team may possess the ball before attempting to score a field goal. It is distinct from the game clock, which displays the time remaining in the period of play. It may be colloquially known as the 24-second clock, particularly in the NBA and other leagues where that is the duration of the shot clock. If the shot clock reaches zero before the team attempts a field goal, the team has committed a shot clock violation, which is penalized with a loss of possession.
In basketball, free throws or foul shots are unopposed attempts to score points by shooting from behind the free throw line, a line situated at the end of the restricted area. Free throws are generally awarded after a foul on the shooter by the opposing team, analogous to penalty shots in other team sports. Free throws are also awarded in other situations, including technical fouls, and when the fouling team has entered the bonus/penalty situation. Also depending on the situation, a player may be awarded between one and three free throws. Each successful free throw is worth one point.
In basketball, a personal foul is a breach of the rules that concerns illegal personal contact with an opponent. It is the most common type of foul in basketball. A player fouls out on reaching a limit on personal fouls for the game and is disqualified from participation in the remainder of the game.
Streetball is a variation of basketball, typically played on outdoor courts and featuring significantly less formal structure and enforcement of the game's rules. As such, its format is more conducive to allowing players to publicly showcase their own individual skills. Streetball may also refer to other urban sports played on asphalt. It is particularly popular and important in New York City.
In basketball, goaltending is the violation of interfering with the ball while it is on its way to the basket and it is (a) in a downward flight (b) above the basket ring and within the imaginary cylinder and (c) not touching the rim. In NCAA & (W)NBA, goaltending is also called if the ball has already touched the backboard while being above the height of the rim in its flight, regardless of it being in an upward or downward flight or whether it is directly above the rim. Goaltending in this context defines by exclusion what is considered a legal block of a field goal. In high school and NCAA basketball, goaltending is also called when a player interferes with a free throw at any time in its flight towards the basket. If goaltending is called for interference with a field goal, the shooting team is awarded the points for the field goal as if it had been made. The team who commits the violation then inbounds the ball at its baseline, the same as if it had conceded a basket. In high school and NCAA basketball, if goaltending is called on a free throw, the shooting team is awarded one point and a technical foul is called against the offending player.
In sports, running out the clock is the practice of a winning team allowing the clock to expire through a series of pre-selected plays, either to preserve a lead or hasten the end of a one-sided contest. Such measures expend time, but do not otherwise have a tactical purpose. This is usually done by a team that is winning by a slim margin near the end of a game, in order to reduce the time available for the opposing team to score. Generally, it is the opposite strategy of running up the score.
In basketball, a flagrant foul is a personal foul that involves excessive or violent contact that could injure the fouled player. A flagrant foul may be unintentional or purposeful; the latter type is also called an "intentional foul" in the National Basketball Association (NBA). However, not all intentional fouls are flagrant fouls, as it is an accepted strategy to intentionally commit a foul in order to regain possession of the ball while minimizing how much time elapses on the game clock.
This glossary of basketball terms is a list of definitions of terms used in the game of basketball. Like any other major sport, basketball features its own extensive vocabulary of unique words and phrases used by players, coaches, sports journalists, commentators, and fans.
The Gus Macker 3-on-3 Basketball Tournament is a nationwide event for players of a variety of age and skill levels in the United States. Although every tournament is different, a typical Gus Macker event involves basketball courts set up in parking lots or closed-off public streets Tournaments are mid-level to major sports media events and are held virtually every weekend from spring through summer.
The Trent Tucker Rule is a basketball rule that disallows any regular shot to be taken on the court if the ball is put into play with under 0.3 seconds left in game or shot clock. The rule was adopted in the 1990–91 season and named after New York Knicks player Trent Tucker, and officially adopted in FIBA play starting in 2010. When the WNBA was established in 1997, this rule was adopted too.
In basketball, the five-second rule, or five-second violation, is a rule that helps promote continuous play. There are multiple situations where a five-second violation may occur.
Delay of game is an action in a sports game in which a player or team deliberately stalls the game, usually with the intention of using the delay to its advantage. In some sports, the delay of game is considered an infraction if it is longer than that permitted according to the game's rules, in which case a penalty can be issued. Some sports that have a delay of game penalty are American football, Canadian football, ice hockey and association football.
The key, officially referred to as the free throw lane by the National Basketball Association (NBA), the National Collegiate Athletic Association (NCAA), and the National Association of Intercollegiate Athletics (NAIA), the restricted area by the international governing body FIBA, and colloquially as the lane or the paint, is a marked area on a basketball court surrounding the basket. It is bounded by the endline, the free-throw line and two side lines, and usually painted in a distinctive color. It is a crucial area on the court where much of the game's action takes place.
In the sport of basketball, the bonus situation occurs when one team accumulates a requisite number of fouls, which number varies depending on the level of play. When one team has committed the requisite number of fouls, each subsequent foul results in the opposing team's taking free throws regardless of the type of foul committed. Teams under the limit are commonly referred to as having fouls to give, and thus they can try to disrupt their opponents without being penalized free throws. These fouls reset every quarter or half depending on the rules in use.
Basketball is a ball game and team sport in which two teams of five players try to score points by throwing or "shooting" a ball through the top of a basketball hoop while following a set of rules. Since being developed by James Naismith as a non-contact game that almost anyone can play, basketball has undergone many different rule variations, eventually evolving into the NBA-style game known today. Basketball is one of the most popular and widely viewed sports in the world.
The FIBA 3x3 World Cup is a 3x3 basketball tournament for national teams organized by the International Basketball Federation (FIBA). The debut of the tournament then named as the FIBA 3x3 World Championship was held in August 2012 in Athens, Greece. The current champions are United States in the men's division and China in the women's division.
