Picture 1: X1 & X2 commence in a tandem. On a pass from O1 to O2, X2 runs out to defend O2. X1 slides back to the free throw line.

Picture 2: As the ball is passed back to O1, X1 comes out to defend O1, and X2 slides back to the lane. When the ball is passed to O3 on the opposite wing, X2 comes out to defend the ball, and once again X1 slides back to the free throw line.

Picture 3: On a skip pass, X1 sprints out to defend the ball (in this case O2), whilst X2 slides to the free throw line.

Defensive positioning, and adjusting whilst the pass is being made, not AFTER the pass is made.

Allow the offense to play live after a certain number of passes. Move one player into the low or high post - defender will have to adjust accordingly.

Initially do not allow the skip pass by the offense, until defenders are comfortable.
