Handlers (1, 2, 3) and "Rail Handlers" (4, 7) make a U shape. Important that 1 & 3 are 5 yards upfield and off sideline. Poppers (5, 6) are offering quick cup breaking options, 10 yards or so upfield.
As the disc moves to the sideline, the handlers off the sideline rotate. Thrower follows his throw, side handler fills to dump, rail handler fills to side.
Side handler VERY QUICKLY looks to the three options on screen in order.
Assuming no upfield throw, side handler swings it back to middle handler. Other side handler cheats up & in as much as possible!
Bro swings it right away!!!!! (Or throws to popper if they're open). #7 switches to the other side as 2 comes over.
Handler follows his throw as always. Same thing happens on the other side now!
Same shit different side.
