How it works
If a defender commits goaltending, the shooting team receives the points the shot would have been worth. Offensive interference can instead erase a basket.
What people often miss
NBA, college, and international rules differ in some details, especially once the ball contacts the rim. A spectacular block can still be illegal if it comes too late.
Why this question comes up
Slow-motion replays often focus on whether the ball had begun descending when it was touched.
