Nah we teach it all the time. The point I'm making is Virginia doesn't have the athletes to run by us and threaten us over top and Perkins doesn't hit those kinds of throws often anyway.
Bandy does it all the time and we had that kind DB play against ND with DBs not scared of the QB or WRs and they played aggressive. Checks on Wimbush on the snap before playing the route. Engage your guy at the LOS and peek in the back field. Didn't mean to keep your eyes in the backfield. Just give a good check to see if he keeps it or the play is designed to come your way.
