I've never noticed Quinn changing the play at the line of scrimmage after reading a blitz is coming ( OL assignment & WR hot routes ) after a play is called from the booth or the sideline communication to his helmet. Communication is cutoff to the QB with 15 seconds left on the play clock. Has he ever audibled to a different play with 15 seconds left on the play clock? Is he allowed to? I've never noticed him doing that and was wondering why . If he has , I don't recall it and beer may have been involved.
