Wedges (1, 2): Always force middle. If not currently the Mark cover the swing to the force side (force the throw center).
Wedges (1, 2): Force middle up the center of the field. If not currently the Mark, cover the swing and as much lane as possible.
Left/Right mid: More or less the same as 3-3-1.
Mid-Mid: Prevent everything up the middle. Highly active.
Short-Deep: Buisiness in the front (Mullet). Short deep is active and pinches in wherever they can. Want to stay slightly ahead of most offense (plays like a mid, but further back).
Deep-Deep: Party in the back (Mullet). Nothing gets behind them.
