Defensive Three-Second Violation

A defensive three-second violation, also known as illegal defense, is a basketball rules infraction in the National Basketball Association (NBA) introduced in the 2001–2002 season. It is assessed when a member of the defending team spends more than three seconds in the free throw lane (also known as the 16-foot lane, or colloquially as "in the paint") while not actively guarding an opponent. To be considered actively guarding, a defender must be within arm's length of an opponent and in a guarding position. A three-second count is suspended if:

a player is in the act of shooting
there is a loss of team control
the defender is actively guarding an opponent
the defender clears the painted area
it is imminent the defender will become legal

In addition, a player guarding an opponent with the ball may be in the paint without actively guarding the opponent.

The team committing a defensive three-second violation is assessed a team technical foul. The offense will receive one free throw and retain possession of the ball.

Prior to the 2001–2002 NBA season, any form of zone defense was considered an illegal defense violation and resulted in a warning on the first violation and then a technical foul for any subsequent violations. However, the defensive three-second violation makes it difficult for NBA defenses to play zone, since zone defenses usually position a player in the middle of the key to stop penetration. The Philippine Basketball Association used to follow the illegal defense rule until the 2003 PBA season when it was abolished and reverted its rule starting in the 2015–16 PBA season. The high school game does not use this rule, nor does European basketball.

The WNBA started using it in 2013.

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 6.75 metres (22 ft 2 in) from the basket in international games and 23 feet 9 inches (7.24 m) in NBA games. A one-point shot can be earned when shooting from the foul line after a foul is made.

Rules and Regulations

Gameplay: A jump ball is a method used to begin or resume play in basketball. Two opposing players attempt to gain control of the ball after it is tossed up into the air in between them by an official.

Positions: During the early years of basketball's evolution, two guards, two forwards, and one center were used.

Equipment: The only essential equipment in a basketball game is the ball and the court: a flat, rectangular surface with baskets at opposite ends.

Official: Basketball is regarded as among the most difficult sports to officiate due to the fast speed of play, the complexity of rules that must be followed, the unique case-specific interpretations of rules, and the instantaneous judgement required.

Violations: 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 it touches a boundary line, or touches any player or object that is out of bounds.

Fouls: An attempt to unfairly disadvantage an opponent through certain types of physical contact is illegal and is called a personal foul.

Strategy: The playbook starts as a canvas picture of the basketball court with all its boundaries and lines. On top of that, the playmaker can draw O's for players on offense, and X's for players on defense.

Slam dunks: A slam dunk, also dunk or dunk shot, is a type of basketball shot that is performed when a player jumps in the air, controls the ball(s) above the horizontal plane of the rim, and scores by putting the ball directly through the basket with one or both hands.
