No. 8: Arizona. Yes, I know the Wildcats showed improvement last season in making it to their first bowl game since 1998. The question is whether they can sustain that upward trend. The loss of four-year starting quarterback Willie Tuitama is one of the most significant in the conference, and although Arizona believes they have talent ready to fill in, there will obviously be some inexperience there. The Wildcats also lost All-Pac-10 picks Mike Thomas at wide receiver and Eben Britten at offensive tackle, so this clearly isn’t the same team that showed that improvement last year. Arizona has a lot to offer in the secondary but the front seven is questionable. The Wildcats should have a strong running game with the combination of Nic Grigsby and Keola Antolin (whom Cal fans know quite well). But it just doesn’t appear Arizona has enough to maintain what it accomplished last season, especially with some other conference teams improving more.
