Yeah, the Big XII is by far #1. A certain 1-loss team SMU drilled (cough: TCU) last year beat the 2nd best team in the Big XII (cough: OU). I had enough CUSA-level football for 4 years <note sarcasm>
SEC had a down year in '05 and Georgia, Alabama, Auburn, LSU, and Florida were all still ranked Top-15. Last year the ACC and Big Ten were better top-to-bottom.
I like some Big XII teams, but there is no parity in the Big XII.. and top to bottom there is no weaker division on either side of the SEC. Much better competition, much better talent. Helluva lot better rivalries.
Arkansas will be fun man.. they're kind of the redheaded step-child of the SEC. Came in as a top-dog in their conference (SWC) and couldn't really compete that well in the SEC.. but they still pack some punch and pull off upsets every once in awhile. They should at least make a bowl this year.
Get ready to call for the hogs. And oh yeah, expect a major @$$-kicking from the Gamecocks in Columbia.
