Regular ho-stack offense set up on the pull.
Defensive sets will provide help over the top. Kind of like a free safety in football. Note the movement of Red 4
Once red 5 moves to top off the defense, our offense should react differently.
The middle offensive cutters should both clear deep. This will likely put three defenders protecting the deep space.
The outside offensive player, blue 1, should then yell, "Poach!" This alerts the handler to see the switch. Blue 1 then moves to the open space in the middle of the field
Now you can see the under cut by 2 or a possible reset to a handler.
