This is a simple drill that, with very little effort, can be used to emphasise various aspects of rebounding. While I don’t use it to initially teach the technical aspects of offensive or defensive rebounding I find it a great drill for revision and to focus on rebounding philosophy in a competitive setting.
Two players begin on either end of the foul line (the elbows). Standing opposite them on the baseline are another two players. One of the players on the baseline has a ball and passes out from under the basket to either player on the foul line. The player on the foul line will catch and shoot the ball.
As soon as the player on the baseline passes out he will run out his opposite player on the foul line. He knows that he will shoot the ball immediately so he is aiming to get to the player and prevent him from rebounding the ball (ie block him out). As soon as the shot is taken the players on the foul line will contest the rebound.
If the players who started on the baseline have done their job they should have blocked out the two players on the foul line and rebounded the ball. If they have done this they then pivot away from the basket and make a quick outlet pass to a coach standing there – with the emphasis on a quick pivot and pass to initiate any fast break opportunities. If they have not done their job and the players on the foul line get possesion they simply try to score in a two on two situation.
