The goal of the drill is to recognize when a teammate is open and how to place a throw when there's pressure defense. We look off too many open unders because we thing the margin is too tight but unless they show us they can bid through an under and get it, we're just looking off open hands.
Our vertical stack play, cuts will be from the front of the stack. Basically whoever is the first person in line (cutter 1), they will make the first cut. Remember to wait a second or two after the person in front of you makes their cut before you make a cut. If you do not get the disc, run to the back of the stack.
