When the thrower needs to reset the disc on the sideline, which should be early in the stall (3-5) They should engage the center handler (1) by turning their body to face them.
If there is an open around pass because the defender is guarding the upline, throw it.
Otherwise, the center handler should cut upline to give space for the far handler (2), who should start approaching either in-line or slightly deeper than the thrower.
When the thrower fakes off (1) and turns to (2), (2) should start running towards the thrower to threaten the upline.
Then once they're at a comfortable throwing distance from the thrower, 2 should turn to the backfield to recieve a pass to reset the stall, with 4 perhaps being in position to recieve a continuation
