This is how I would rank this list. I really think Iowa would win big over ASU this year, for revenge if nothing else. I also do NOT think scUM is a better team than Cal, and depending on where the game is, I think Cal would win. meshitagain just doesn't have the horses on defense, and say what you want about their offense, they're starting two sophomores at the most critical positions and lost their only threat in Edwards. There could be some huge growing pains at QB this year.
It's always tough to rank conf. vs. conf., especially when you're biased (as everybody here tends to be). Little things like who has home field advantage could be the difference maker in a lot of these games. But, I really think the advantage would go to the Big 10, if for no other reason than defense. OSU, Purdue, and Penn State all return at least nine starters on defense, and all were above-average to very good last year. Wisky will always have a tough D, and Michigan State's D will likely be better than any Pac 10 opponent.
From a talent perspective, I really see the Big 10 and the SEC as tops in the country this year. From top to bottom in the conferences, there are more potential pitfalls in those conferences than anywhere else. I mean, compare Oklahoma's or USC's schedule to LSU's or OSU's....no contest.
