I know I'm going to get hammered for this but here's my view on the toughest conference...the Big 10, stop laughing . My theory is this in the Big 10 you have Michigan, Ohio St., Michigan St., Wisconsin and Penn St. who are traditionally in or around the top 25 if not 15. Purdue,Iowa, Illinois and Northwestern can jump up in any year and win a title too. The only real door mats in the league are Indiana and Minnesota who have had great offenses lately. This conference just like the SEC beats the shit out of each other and makes it tough to go undefeated and win a title for any of them. The SEC is a close second, I love watching their games. They like the Big 10 just pound each other till the last minute every week, I think it's a matter of style preferance between those two conferences but I laugh when people talk about the Big 12. Nebraska hasn't had any competition in years until lately and people always claim that their schedule is so tough. Sure Texas, OU, and Collorado are in there but they just came up again lately and after that there's nothing. College football is one of the best sports to watch period and I think that the rankings system helps alot. People love to argue and with a playoff it would take away a bit I think personally.
