A simple 1-2-1-1 press break. 5 is long. 3 looks to get the ball out and in before the defence can get set. The inbounds pass should go to 1. If the pass is ballside, 4 moves to the middle, 3 stays behind the ball as an safety. If the inbounds pass goes to 1 on the other side, 4 stays on the sideline, 2 flashes to the middle.
If there is no press, 2 and 4 release long into a secondary break.
"80" press break - Since the defence will often trap an inbounds pass to the corner, with varsity players the first look is 2 and 4 up the sidelines. On the pass to 1, ballside 2 moves up the sideline looking for a pass over the top. If 1 passes to 3, 1 circles back behind 3.
