I think it's the coaching styles that give CBJ trouble. Spurrier was an offensive guy, he wants to outscore everyone and play a little D.
Muschamp wants to win with a little offense and a stout D. I think he has CBJ figured out enough to slow our offense.. especially if they have an off day like last year. I don't think it's so much as he is in CBJ's head but instead that he is a good defensive coach and has had decent matchups against us.
And if our D is having an off day (or season) for whatever reason then it compounds the problem.
