I think the change in DB technique was a Taver Johnson change. I remember at least one quote from him defending the practice. Schiano used to coach the safeties and never taught that to my knowledge. Schiano was in charge of the defensive scheme, and he deserves blame for its failures, but Coombs had guys turning to locate the ball under Schiano's scheme. Find it hard to believe the change resulted from Schiano when we brought in a new DBs coach.
