If you want to talk about SOS, it is certainly the Big 10/11/12 that has to do the catching up. EVEN IF the SEC continues with Western Carolina, Furman, Georgia State, et. al., the SEC SOS is fearsome, indeed. Just by virtue of the fact that every SEC team plays 8 conference games, and the SECC (which is considered a regular season game, NOT post-season) makes it 9 for two conference teams, the SEC teams top to bottom have the toughest schedules on average year in and year out. Second place is not even close. Where is my proof? Just look at how the SEC completely owns the polls year after year - ridunculous stuff like 3 of the top 5, 7 of the top ten, and 9 in the top 25...stuff like that. Not to mention the stranglehold we have on the crystal football.
In sum, it does not matter who we play OOC. The conference schedule we play makes up the true SOS by a country mile. I think Ole Miss could have beaten Ohio State last year.
