BASKETBALL

Basketball is a team sport in which two teams of five active players each try to score points against one another by propelling a ball through a 10 feet (3 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 shooting the ball through the basket above; the team with more points at the end of the game wins. The ball can be advanced on the court by bouncing it (dribbling) or passing it between teammates. Disruptive physical contact (fouls) is not permitted and there are restrictions on how the ball can be handled (violations).

Through time, basketball has developed to involve 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, the shortest member usually plays "point" while often the best ball handlers are guards. 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 have become exceedingly popular as an outdoor sport among both inner city and rural groups.

A basketball is an inflated spherical ball used in the game of basketball. Basketballs typically range in size from very small promotional items possibly only a few inches in diameter to extra large balls nearly a foot in diameter used in training exercises to increase the skill of players.[1] Nearly all basketballs have an inflatable inner rubber bladder, generally wrapped in layers of fiber and then covered with a tacky surface made either from leather (traditional), rubber, or a synthetic composite. As in most inflatable balls, there is a small opening to allow the pressure to be increased or decreased. The surface of the ball is nearly always divided by "ribs" that are recessed below the surface of the ball in a variety of configurations and are generally a contrasting color. A standard 29.5 inch basketball has about 4118 pebbles, with the pebbles being at a diameter of 2.5 millimeters. An orange surface with black ribs and a possible logo is the traditional color scheme of basketballs but they are sold in various colors. Balls are generally designated for indoor (generally made of leather or absorbent composites), or all-surface use (generally made of rubber or durable composites, also known as Indoor/Outdoor balls). The abrasiveness of asphalt and the dirt and moisture generally present in an outdoor setting will usually ruin an indoor ball within a very short period of time.Jonathan B is the best basketball player.

Aside from the court and the baskets, the basketball is the only piece of equipment necessary to play the game of basketball. During the game, the ball must be bounced continuously (dribbling), thrown through the air to other players (passing) and towards the basket (shooting). Therefore, the ball must be very durable and easy to hold on to. The basketball is also used to perform tricks (sometimes called freestyling), the most common of which are spinning the ball on the tip of one's index finger, dribbling in complex patterns, rolling the ball over one's shoulder, or performing aerobatic maneuvers with the ball while executing a slam dunk, most notably in the context of a slam dunk contest.

Dribbling

Dribbling is the act of bouncing the ball continuously, and is a requirement for a player to take steps with the ball. To dribble, a player pushes the ball down towards the ground 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 travel from the floor to the hand, making it more difficult for the defender to "steal" the ball. Additionally, good ball handlers frequently dribble behind their backs, between their legs, and change hands and directions of the dribble frequently, making a less predictable dribbling pattern that is more difficult to defend, this is called a crossover which is the most effective way to pass 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 someone stealing the ball from him/her.

Blocking

A block is performed when, after a shot is attempted, a defender attempts to alter 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 part of its arc; this is known as goaltending. It is also illegal 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 at the taller power forward or center positions generally record more blocks than players at the shorter guard positions. However, with good timing and sufficient vertical leap, even shorter players can be effective at blocking 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 defense 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 being impossible to intercept. Good passers can pass the ball with great accuracy and touch and know exactly where each of their teammates like 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 them effectively, many coaches discourage no-look or behind-the-back passes, believing them to be fundamentally unsound, difficult to control, and more likely to result in turnovers or violations.

Shooting Player releases a short jump shot, while her defender is either knocked down, or trying to "take a charge." 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 can be outlined here.

The player should be positioned facing the basket with feet about shoulder-width apart, knees slightly bent, and back straight. The player holds the ball to rest in the dominant hand's fingertips (the shooting arm) slightly above the head, with the other hand on 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 bending and extending the knees and extending the shooting arm to become straight; the ball rolls off the finger tips while the wrist completes a full downward flex motion. When the shooting arm is stationary for a moment after the ball released, it is known as a follow-through; it is incorporated to maintain accuracy. 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 will profess proper arch. Most players shoot directly into the basket, but shooters 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, 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 returning the feet to the ground is 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.

A slam dunk (or simply a dunk) is a type of basketball shot that is performed when a player jumps in the air and manually powers the ball downward through the basket with one or both of his hands over the rim.[1] This is a standard field goal worth two points. The term "slam dunk" was first coined by the late Los Angeles Lakers announcer Chick Hearn.[2] Prior to that, it was known as a dunk shot.[1]

The slam dunk is one of the highest percentage field goals one can attempt in basketball as well as one of the most crowd-pleasing plays. Other terms for slam dunk include "jam", "stuff", "flush", "cram" or "throw down.

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-handler may not move both feet without dribbling, 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. The ball may not be kicked nor 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.

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 (the lane, or "key") (3 seconds). These rules are designed to promote more offense.

No player may interfere with the basket or ball on its downward flight to the basket, or while it is on the rim (or, in the NBA, while it is directly above the basket), a violation known as goaltending. If a defensive player goaltends, the attempted shot is considered to have been successful. If a teammate of the shooter goaltends, the basket is cancelled and play continues with the defensive team being given possession.

Traveling is a violation of the rules that occurs when a player holding the ball illegally moves one or both of his feet. Most commonly, a player travels by illegally moving his pivot foot or taking too many steps without dribbling the ball. However, this rule is now obsolete in the National Basketball Association and is rarely, if ever, enforced

a double dribble is a violation in which a player dribbles (bounces) the ball, clearly holds it with a combination of either one or two hands (while either moving or stationary), and then proceeds to dribble again without first either attempting a field goal or passing off to a teammate.

Fouls

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 (4.5 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. The calling of fouls can vary between games, leagues and even between referees.

A player or coach who shows poor sportsmanship, for instance, 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 (which unlike a personal foul, the other team can choose who they want to shoot the free throws) 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 unsportsmanlike fouls (or flagrant fouls in the NBA) and typically will result in ejection.

If a team surpasses a preset 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 fouls for that period, the number depending on the league. In the US college game if a team surpasses 7 fouls in the half the opposing team is awarded a one-and-one free throw (make the first you have a chance at a second). If a team surpasses 10 fouls in the half the opposing team is awarded two free throws on all subsequent fouls for the half. A player who commits five fouls, including technical fouls, in one game (six in some professional leagues, including the NBA) is not allowed to participate for the rest of the game, and is described as having "fouled out".

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.)

The number of free throws awarded increases with the number of fouls committed. Initially, one shot is awarded, but after a certain number of additional fouls are committed the opposing team may receive (a) one shot with a chance for a second shot if the first shot is made, called shooting "one-and-one", or (b) two shots. If a team misses the first shot (or "front end") of a one-and-one situation, the opposing team may reclaim possession of the ball and continue play. 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" because of the basket made at the time of the foul (2 points) and the additional free throw (1 point). Four-point plays, while rare, can also occur.

a technical foul is any violation of the rules which does not involve physical contact during the run of play between players on the court, i.e., any violation which is not a personal foul. The most common technical foul is for unsportsmanlike conduct. Technical fouls can be assessed against players, bench personnel or even the entire team.

Technical fouls are handled slightly differently under international rules than under the rules used by the various competitions in the United States. Firstly, illegal contact between players on the court is always a personal foul under international rules, whereas in the USA, such contact is (with some exceptions) a technical foul (rather than a personal foul) when the game clock is not running. Secondly, in FIBA play, players foul out after five total fouls, both technical and personal. In the USA, players are allowed five personal fouls in amateur play and six in professional play before they are disqualified. They can also be disqualified for excessive (typically, two) technical fouls as well.

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. Due to the nature of the game, personal fouls occur on occasions and are not always regarded as unsportsmanlike. However, a contact foul involving excessive or unjustified contact is classed as an unsportsmanlike foul (or in the NBA, flagrant foul).

an ejection (or dismissal or sending-off) is a disqualifying action assessed to a player or coach by a game official (such as a referee or umpire), usually for unsportsmanlike conduct.

Many ejections occur for such actions as fighting (or attempting to instigate a fight) and persistent arguing with a game official. Usually, a warning is given to the offender before he/she is actually ejected.

When the offender is ejected, he/she must leave the immediate playing area; in most cases, this means going to the locker room or other part of the venue out of sight of the playing area, or leaving the stadium grounds. If a player or coach refuses to cooperate, additional sanctions may be levied (such as forfeiting a contest or being suspended).

Positions and structures

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:

1. 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 2. shooting guard: creates a high volume of shots on offense; guards the opponent's best perimeter player on defense 3. 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 4. 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) 5. center: uses size to score (on offense), to protect the basket closely (on defense), or to rebound.

Point guard (PG), also called the one or "the ball-handler", is one of the standard positions in a regulation basketball game. Point guards are often the smallest players on the court with a notable exception being Magic Johnson. A point guard has perhaps the most specialized role of any position. Essentially, the point guard is expected to run the team's offense by controlling the ball and making sure that it gets to the right players at the right time. Above all, the point guard must totally understand and accept his coach's game plan. The position can be compared to a quarterback in football. This means knowing when and how to instigate a fast break and when and how to initiate the more deliberate sets.

The Shooting guard (SG), also known as the two or off guard,[1] is one of five traditional positions on a basketball team. Players of the position are often shorter, leaner, and quicker than forwards. A shooting guard's main objective is to score points for their team.[1] Some teams ask their shooting guards to bring up the ball as well; these players are known colloquially as "combo guards". A player who can switch between playing shooting guard and small forward is known as a swingman.

The small forward, or, colloquially, the three, is one of the five positions in a regulation basketball game. Small forwards are typically somewhat shorter, quicker, and leaner than power forwards and centers, but on occasion are just as tall. The small forward position is considered to be perhaps the most versatile of the main five basketball positions, due to the nature of its role. Most current NBA small forwards are between 6'5"/1.96 m and 6'9"/2.06 m in height.

Power forward is a position in the sport of basketball. The position is referred to in playbook terms as the four position and is commonly abbreviated "PF". Power forwards play a role similar to that of center in what is called the "post" or "low blocks". They play offensively with their back to the basket on offense and position themselves defensively under the basket in a zone defense or against the opposing power forward on defense in man-to-man defense.

The center, colloquially, the five, is one of the standard positions in a regulation basketball game. The center is normally the tallest on the team, and often has a great deal of strength and body mass as well. A typical NBA center is 6'10" (2.08 m) or taller.

the basketball court is the playing surface, consisting of a rectangular floor with baskets at either end. In professional or organized basketball, especially when played indoors, it is usually made out of a hardwood, often maple, and highly polished. Other indoor surfaces include suspended plastic interlocking tiles from companies like Mateflex, Flex court, Rhino Court and Sport Court. Outdoor surfaces used include plastic interlocking tiles (suspended athletic courts), asphalt, blacktop, or similar materials are used. Amateur players would typically use tarmac as the surface.
