What it is
- Goaltending and Basket Interference is a fundamental basketball concept that goaltending occurs when a defensive player interferes with a shot while it is on its downward.
- Technically, any contact with the ball on its way down counts as goaltending—this is not subjective; if the ball is demonstrably descending and a defender touches it, the basket.
- Conversely, if a defender blocks a shot on its upward trajectory, no violation occurs.
How it works
- Technically, any contact with the ball on its way down counts as goaltending—this is not subjective; if the ball is demonstrably descending and a defender touches it, the basket counts.
- Conversely, if a defender blocks a shot on its upward trajectory, no violation occurs.
- Modern replay technology has clarified the "downward trajectory" determination at the highest levels.
- Basket interference, committed by either offense or defense, occurs when a player touches the ball while it is on or in the basket (except after it has come to rest on the rim).
- An offensive player dunking the ball and accidentally hanging on the rim after releasing the ball is not basket interference.
