This is our basic Vert Stack set up
When "Washington" is called, the #2 in the Stack (the guy next to the Stack Setter), fakes in a few steps to the OPEN side, then cuts DEEP.
As #2 cuts deep, the defender at the back of the stack has to DROP to help cover the deep cut. This allows cutter #5 to have an Open cut UNDER.
Enter step description...
The Handler with the disc can throw to the open underneath cutter for an easy gainer.
The Defense either has to Switch or leaves an uncovered Cutter. After the first throw, We can either take the Open DEEP look, or continue our Vertical Stack as normal.
The Deep Cutter can come under next, keeping our offense moving.
