I like the under in this game. Looking at SC they've handled both Oregon St and Wazzu pretty handily and both have similar spread passing attacks like Cal. Seems like more of the running spread teams have been ones that have given SC fits. In addition, they get a pretty good pass rush with their front 4 so they can drop 6-7 into coverage and Cal does not throw the ball to their back a ton. Having said that, I'll probably be completely wrong.
I also like USC in this game, despite Cal having played very, very well this year. Cal also has Stanford on deck FWIW. Same can be said for USC though with UCLA.
