Setting up the Drill:   Line all players up behind the foul line (if you have a larger team, you may divide the group in half and use both basketball goals to play the game).  The first two people in the line will have basketballs.   

The Drill:   When you say go, the first player will shoot the ball rom the foul line.  If they make the shot, they will retrieve the ball and give it to the next player in line without a ball.  If the player misses the shot, they will rebound the ball and continue shooting until they make the shot.  The second player in line will start shooting as soon as the first player takes a shot.  If the second player makes the shot before the first player then player one is out for the remainder of the game.  The drill does not stop until there is only one player left.
