They're only college football opinions, but at least they're all mine:
" If, as some believe, Lane Kiffin has been holding back some of his offensive playbook for later in the season, he shouldn't hold anything back on Saturday. If he does, he'll have a difficult time outpointing Arizona's high-scoring spread offense.
" The over-under for the Trojans-Wildcats is 65 points. Considering the score last year was 48-41 and the two teams combined for 1,136 yards, I'd take the over.
