Hi guys. First-time poster here.
Here's the play:
Quarterback A12 retreats into his own end zone as if to pass. Before he can throw, B72 grasps and twists his face mask so that A12's helmet comes completely off his head. I am thinking the result of the play is a safety, since you would shut it down as soon as the helmet came off the runner's head. But is the enforcement spot the previous spot or the goal line? Appreciate your thoughts.
