We use a 1-4 alignment in our Full Court Press Break Set. We call the set "Homerun" and out of it we have our Man press break calls and zone press break calls. Below is our very simple press break for FC M-2-M pressure.
Line up in a 4 across set with the 1 lined up away from the ball.
2 on the opposite side and 3 and 5 at the elbows.
5 must be on the same side as 1
2 fakes towards the ball and runs deep. 3 and 5 set a double cross screen for 1 to come off heading towards the ball. 1 catches and waits for every one to clear before dribbling.
