Purdue fan here. Which is tough, because every time we seem on the verge of actually becoming an elite team, something inevitably goes wrong (see: 2003, 2004).
Agree that the SEC is the best conference this year. LSU probably should be the #1 team, but they have a habit of making games way too difficult for themselves. I wouldn't say every team in the SEC is "exceptionally" good, though. Kentucky and S. Carolina were overrated. Good, but not top 10 good. But being overrated is certainly NOT unusual this year (see: Cal, S. Florida, BC, USC, Wisconsin).
Florida and Auburn are the other two SEC teams I think have top 10 talent. Georgia, Tennessee, and Kentucky all seem like 10-20 level teams to me.
People were hating big time on the Big 10 being down earlier this year, but in all honesty, the ACC and the Big 12 are in exactly the same position. And wait for it - Kansas will lose to Missouri. I don't think I've seen an easier schedule than their's from a top 10 team.
The Pac-10 needs to shut it - can't believe some of them seriously considered themselves the best conference in the nation. They're good, but not all that. Guess who ND's only win of the season was against? Oh right - @ UCLA. Embarrassing. (Although to be fair, Northwestern from the Big 10 lost to Duke, of all teams. But at least Northwestern isn't turning around and beating the Big 10's "best" teams, like UCLA did by beating Cal.)
Final thought: I might cry if Michigan wins the Big 10 this season. Did they really have to lose to a D-II team before they suddenly realized they actually have talent? Sigh.
