All plays start with a 3-4 vertical set.
A (the call is giving by saying an animal or vegetable beginning with the letter in question): Break-side dump handler cuts straight up the line.
This play can be useful as most defenses expect the cutter to make the first move in the set-play.
B: Everyone floods to the open-side.
Then the second-in-stack cuts back to the break-side by himself.
The key here is to drag poaches out of any dangerous areas. Cut out of the endzone if you have to.
C: Front of stack cuts one way, second the other; third comes straight under.
