Setup with 3 handlers & 4 cutters. Stack should sit in the middle of the endzone to create more space for dump handlers to attack open side of endzone.
Middle handler [2] sets up an upline cut. Far handler [3] creeps closer.
[2] goes upline, [3] sets up an upline cut. Front of stack [4] starts to prepare for a fill cut.
[4] gets the dump, handlers [2] & [3] continue to clear to back of stack.
Original back of stack [7] provides break side continuation while new front of stack [5] provides open side option.
