As I said, one of the keys to defending the option is recognizing that the snap count will always occur when the pitch man is either right behind the quarterback or just a couple steps away. If your defensive linemen know when the ball will be snapped, they can get upfield, prevent Tech's offensive linemen from diving at their knees, and keep Nesbitt from reaching the corner.
Miami had an advantage because Dwyer was hurt. But the principles remain the same. Force Nesbitt to throw the ball. On occasion, he will connect on a a big play, but he's not accurate enough to do it consistently.
