In basketball, we often hear the term "interfering with the ball". So, what is a jamming ball?Interference is a point scored when the ball is in the cylinder area of the basket during the shooting process, if the defender touches the ball, regardless of whether the ball goes into the basket. This rule is to protect the rights and interests of the attacking players and avoid affecting the fairness of the game due to illegal interference by the defensive players.
The rule of ball interference dates back to 1932, when the American Basketball Association (BAA) instituted it to settle some of the controversies in the game. Over time, the rule of interference ball has gradually been accepted by national basketball organizations and has become popular worldwide.
There are a few key factors to consider when judging whether a shot is being affected by an interfering ball:
1.Completion of the shot: When the offensive player throws the ball, if the ball is still on the rise or has not yet touched the basket, then the shot is considered unfinished. In this case, even if a defender touches the ball, it does not count as an interference ball.
2.Position of the defender: When the defender is standing in the cylindrical area of the basket, his body or arms cannot touch the basketball that is rising or falling. Otherwise, the shot is considered to have been affected by the interference ball.
3.Defensive Intent: If a defender deliberately uses his or her arms to block the basketball, then the shot is considered to have been affected by the interference ball. However, if the defender only inadvertently touches the basketball, then the shot is not affected by the interference ball.
It's important to note that the jamming rule doesn't apply to shots from beyond the three-point line. In addition, during a free throw, whether the defender touches the basketball or not, it will not affect the outcome of the free throw.
