You are right, and I had forgotten that. Their history of winning games when the opponent has had an extra week or more to prepare for the option attack is very poor, however. There is a good reason why almost all teams left that offense for something better (and many teams, including Clemson, used to run the option). A DL that can clog the running lanes, and LB's and Corners who can outrun the pitch folks pretty much render it ineffective. It does require strict discipline, and it goes against the norm that has everybody swarming to the ball.
