You will need at least 8 players. 2 offensive and 2 defensive players will assemble to play 2v2 on one end of the floor. The other players will form lines out-of-bounds on either side of the free throw line extended.
Play will begin as the players begin playing 2v2. Once the defence gets the ball, they immediately throw the ball to either of the 2 players waiting on the sidelines. The players that were on offense sprint back to try and prevent the 2 new offensive players from scoring in transition. This pattern continues full court.

This drill emphasises communication, picking up the open player; sprinting back and finding a player to defend.
