Watch the scene where Elliot is the hoops player. When he dunks the ball and the backboard shatters, it shatters AFTER he lets go of the rim. But, when they show the replay, the rim shatters BEFORE he lets go of the rim.
Don't forget the guys talking in the background......they mention the broken backboard before it shatters. He was supposed to pull the rim twice.....the first time it was after the second pull the second time it was before the second pull.
