The ball starts with CB, who passes to the running in LB.
LB moves close to the left side of the defense and passes slantwise backwards to CB, who runs in to the left.
RB has started a fast running in and receives the ball from CB and shoots.
Remember to practice both sides.

The exercise can also be performed with wing, backcourt and center backcourt.
Further more LB can choose to pass to RB, who passes the ball to CB.
RB must then start her running in earlier than before and CB must hesitate a bit before running in.
