Basketball is a team sport, the objective being to shoot a ball through a basket horizontally positioned to score points while following a set of rules. Usually, two teams of five players play on a marked rectangular court with a basket at each width end. Basketball is one of the world's most popular and widely viewed sports.
A regulation basketball hoop consists of a rim 18 inches (46 cm) in diameter and 10 feet (3.0 m) high mounted to a backboard. A team can score a field goal by shooting the ball through the basket during regular play. A field goal scores two points for the shooting team if a player is touching or closer to the basket than the three-point line, and three points (known commonly as a 3 pointer or three) if the player is behind the three-point line. The team with the most points at the end of the game wins, but additional time (overtime) may be issued when the game ends with a draw. The ball can be advanced on the court by bouncing it while walking or running (dribbling) or throwing (passing) it to a team mate. It is a violation to move without dribbling the ball (travelling), to carry it, or to hold the ball with both hands then resume dribbling (double dribble).
Various violations are generally called "fouls". Disruptive physical contact (a personal foul) is penalized, and a free throw is usually awarded to an offensive player if he is fouled while shooting the ball. A technical foul may also be issued when certain infractions occur, most commonly for unsportsmanlike conduct on the part of a player or coach. A technical foul gives the opposing team a free throw, and the opposing team is also retained possession of the ball.
Basketball has evolved many commonly used techniques of shooting, passing, dribbling, and rebounding, as well as specialized player positions and offensive and defensive structures (player positioning) and techniques. Typically, the tallest members of a team will play "center", "power forward" or "small forward" positions, while shorter players or those who possess the best ball handling skills and speed play "point guard" or "shooting guard".
While competitive basketball is carefully regulated, numerous variations of basketball have developed for casual play. Competitive basketball is primarily an indoor sport played on a carefully marked and maintained basketball court, but less regulated variations are often played outdoors in both inner city and remote areas.
Creation
In early December 1891, Canadian American Dr. James Naismith, a physical education professor and instructor at the International Young Men's Christian Association Training School (YMCA) (today, Springfield College) in Springfield, Massachusetts, USA), was trying to keep his gym class active on a rainy day. He 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 the bottom of the basket was removed,allowing the balls to be poked out with a long dowel each time.
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.
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. 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 in Albany, New York on January 20, 1892 with nine players. The game ended at 1–0; the shot was made from 25 feet (7.6 m), 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.
History of Basketball
James Naismith was a Canadian American physical education instructor at the International YMCA Training School in Springfield, Massachusetts. In December 1891 , the director of the school, Dr. Luther Halsey Gulick, asked Naismith to find a physical activity to occupy a "class of incorrigibles." Naismith may have other motivations as well. Naismith wanted to create a game of skill for the students instead of one that relied solely on strength. He needed a game that could be played indoors in a relatively small space. And he wanted to keep his football players in shape off-season. As a kid Naismith played a game called duck on a rock. He took account of the game he played as a kid and made it into what we now call basketball. With the help of his wife he devised a game suitable for a gymnasium.
Naismith obtained two peach baskets and a soccer ball, and developed 13 rules for the new game. He divided his class of 18 into 2 teams of 9 players each (the team today would be the equivalent of 3 guards, 3 centers, and 3 forwards) and set about to teach them the basics of his new game of Basketball.
The object of the game was to throw the soccer ball into the fruit baskets nailed to the lower railing of the gym balcony. Every time a point was scored, the game was halted so the janitor could bring out a ladder and retrieve the ball. Later, the bottoms of the fruit baskets were removed.
The first public basketball game was in Springfield, MA, on December 21, 1891.
The First 13 Rules of Basketball
1. The ball may be thrown in any direction with one or both hands.
2. The ball may be batted in any direction with one or both hands (never with the fist).
3. A player can run with the ball. The player must throw it from the spot on which he catches it, allowance to be made for a man who catches the ball when running at a good speed.
4. The ball must be held in or between the hands; the arms or body must not be used for holding it.
5. No shouldering, holding, pushing, tripping, or striking in any way the person of an opponent shall be allowed; the first infringement of this rule by any player shall count as a foul, the second shall disqualify him until the next goal is made, or, if there was evident intent to injure the person, for the whole of the game, no substitute allowed.
6. A foul is striking at the ball with the fist, violation of Rules 3, 4, and such as described in Rule 5.
7. If either side makes three consecutive fouls, it shall count a goal for the opponents (consecutive means without the opponents in the mean time making a foul).
8. A goal shall be made when the ball is thrown or batted from the grounds into the basket and stays there, providing those defending the goal do not touch or disturb the goal. If the ball rests on the edges, and the opponent moves the basket, it shall count as a goal.
9. When the ball goes out of bounds, it shall be thrown into the field of play by the person first touching it. In case of a dispute, the umpire shall throw it straight into the field. The thrower-in is allowed five seconds; if he holds it longer, it shall go to the opponent. If any side persists in delaying the game, the umpire shall call a foul on that side.
10. The umpire shall be judge of the men and shall note the fouls and notify the referee when three consecutive fouls have been made. He shall have power to disqualify men according to Rule 5.
11. The referee shall be judge of the ball and shall decide when the ball is in play, in bounds, to which side it belongs, and shall keep the time. He shall decide when a goal has been made, and keep account of the goals with any other duties that are usually performed by a referee.
12. The time shall be two 15-minute halves, with five minutes' rest between.
13. The side making the most baskets in that time shall be declared the winner. In case of a draw, the game may, by agreement of the captains, be continued until another goal is made.
The first basketball game
On December 21, 1891, James Naismith defined a new game using five base ideas and thirteen rules. That day, he asked his class to play a match in the Armory Street court: 9 versus 9, using a soccer ball and two peach baskets. Frank Mahan, one of his students, wasn’t so happy. He just said: "Huh. Another new game". However, Naismith was the inventor of the new game. Someone proposed to call it “Naismith Game”, but he suggested "We have a ball and a basket: why don’t we call it basket ball"? The eighteen players were: John J. Thompson, Eugene S. Libby, Edwin P. Ruggles, William R. Chase, T. Duncan Patton, Frank Mahan, Finlay G. MacDonald, William H. Davis and Lyman Archibald, who defeated George Weller, Wilbert Carey, Ernest Hildner, Raymond Kaighn, Genzabaro Ishikawa, Benjamin S. French, Franklin Barnes, George Day and Henry Gelan 1–0. The goal was scored by Chase. There were other differences between Naismith’s first idea and the game played today. The peach baskets were closed, and balls had to be retrieved manually by cutting a small hole in the bottom of the peach basket and poking the ball out using a stick. Only in 1906 were metal hoops, nets and boards introduced. Moreover, earlier the soccer ball was replaced by a Spalding ball, similar to the one used today.
Fouls
The referee signals that a foul has been committed.
Main articles: Personal foul (basketball) and Technical foul
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 15 feet (4.6 m) 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 among 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 among leagues. Repeated incidents can result in disqualification. A blatant foul involving physical contact that is either excessive or unnecessary is called an intentional foul (flagrant foul 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 player will be awarded one additional free throw for one point. In combination with a regular shot, 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
Main article: Basketball position
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, mainly long-ranged; and 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 their 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.
