Starting in the middle of the field the "wall" cannot allow anything through the middle.
When the play swings to the outside, the wall follows forcing to the sideline. 3 is brought back to help guard the sideline. 5 falls back to help deep and 4 pinches under to stop the easy swing.
4 will release the mark and go back once the dump is in the same 1/3 of the field.
When a crash occurs, it is more important to stay a wall than to stop the reset. we will address too many resets if it happens, but we need to make sure the wall does not get broken.
If we get broken. We must have an aggressive mark to prevent further damage until the wall can recover.
Wall recovers
Mark is free to leave
