Start in vert stack. Use handler resets if necessary to give cutters time to gtfo. Stack a little far, give room to handlers.
Breakside Handler cuts upline. Hit it if it's open. Score? Done. If not, continue.
If the upline didn't score, look for a continue from the stack (back or poached player - can be called by the stack). If this throw is not open, you are back at step 1 (closer to endzone now)
Back to step 1 (whether upline worked or not)
Breakside cuts upline, does NOT get it (chump)
Front of stack cuts in to the breakside. Thrower should hopefully have this throw (fake big to force side, step way around - we can lose vertical yards if we need to since this is a reset and gaining breakside yards). Upline handler resets into the stack.
Thrower (was center) immediately cuts upline to breakside. If we get the throw off while #3 defender is sealing, score.
If that breakside throw doesn't happen, that handler resets to the stack and the front of the stack cuts straight downfield for a centering pass. Back to step 1.
