As soon as the 1 man gets the ball back, the 5 sets a back pick on the 4 and 1 attempts a lob pass to the 4. If the lob pass is not there, then the 5 man rolls hard down the lane after the pick and 1 passes to the 5.
This can be run from the other side with the 3 and 4 lining up together up top. Addtitionally, we can switch the 4 and 5 men so the defense gets another look.
