Back Door

Entertainment / Basketball / Back Door: A back door play is when a player without the ball gets behind the defense and receives a pass for an easy score. This can be executed if the defenders are unaware of the open space behind them. Also, when a defender overcommits on defense (e.g. Tries to steal or deny a pass), they are vulnerable to a backdoor play. Most notably used by Pete Carril's team at Princeton University.
