normal EZ set, but with the disc on one of the sidelines
if super open, we can immediately throw the swing to the middle.
Enter step description...
Otherwise, handler cuts upline. again, we can throw to the upline if it is super open.
front of the stack fills in; notice 3rd handler stays wide (all the way on far sideline!) to prevent a poach D
continuation cuts from the front, or swing all the way across
