Too many, I personally don't bet and if I did would never bet against OSU especially. Any given saturday.....
On a personal note, I hope this past weekend was all part of Tressels Jedi mind tricks for USC, but props to the Bobcats for giving it their best. I think OSU has as good a team as USC and this game will come down to who wants it more and coaching. This is where Tressel is weak in my opinion, in his loyalty to players, his conservative play calls, and lack of creative play calling.
Just my .02
