Players line up on the court as per in the diagram. 1 passes the ball to 5, 2 to 6, 4 to 7, and 3 to 8. The following rotations are the same for all players:

1 passes to 5, 5 passes back to 1
5 then defensive slides up to the elbow and receives the pass from 2 and passes the ball back
5 then defensively slides diagonally across the key to the opposite block and receives a pass from 3 then passes the ball back
5 then slides up to the elbow and receives the passes from 4 then returns the pass

Focus is on quick, hard passes and defensive stances. Drill for 2 or 3 minutes.
