The ball starts with LW, who passes to CB, who is running in to the right.
Now LB crosses behind CB, receives the ball and runs against the center.
The ball is passed on to RB, who moves in and pass to the running in LW.
LW passes to RW and the exercise can start all over again from this side.
If defending backcourt players are used the running in wing remains on the backcourt position and the opposite "defending backcourt" runs to the LW position.
Start with 2 wings in the ball side.
The exercise can be performed as a game exercise with only 1 player on the back court positions.
