A Dead-Ball Rebound is a kind of rebound that a player or a team can get in three ways.
One is when there is a miss on the first foul shot during a two-shot foul or the first two shots of a three-shot foul.
Another is when a player shoots the ball, bounces off the rim, and the end buzzer sounds off before either team gets control of the ball.
Lastly is when a player shoots the ball and then hits the shot clock.
Essentially, it is a rebound that doesn't count toward a player's or team's total rebound stats. It happens in specific situations when the ball is considered "dead" or out of play.
Dead-ball rebounds are still tracked to keep the box score accurate, ensuring every missed shot has a corresponding rebound. However, they don't affect a player's rebound numbers.
