Most of them tend to avoid playing a decent schedule in the process. Auburn play five top twenty teams, Oregon play none.
Every year people pimp the likes of Oregon and Wisconsin and come the Championship game they get bent over by a SEC team.
The SEC teams play those teams not by choice, but because they are conference games. If they didn't have to they wouldn't either. Also the SEC doesn't always win.
I don't really see the argument. If your contention is that the SEC is the strongest conference, it probably is, then they should have no problem winning a playoff every year.
Do the SEC want a playoff system or do they prefer the current biased system that will almost always guarantee an SEC team in the BCS title game? I know the rest of the nation would probably prefer a playoff and let the actual best team win, SEC or not.
That said, I don't think Oregon is number 1, and I attend U of O. Nor do I think Auburn is number 1. I think the two top programs in the country THIS year are TCU (they are a monster and anyone who denies it is delusional) and Wisconsin has come on like a run away train. They are undoubtedly the hottest team in college football at the moment and I think they would run over Auburn or Oregon.
You should also check your facts. Oregon played and beat Stanford, the current number 4, they just beat Arizona which are hovering in and around the top 20.
The reason people pimp the likes of "Oregon and Wisconsin" which come from very legitimate conferences, hello Ohio State, hello USC, I think you actually mean the likes of Hawaii, TCU and Boise, is because people in general would rather see the actual best team in college football crowned champions, not a team from the most powerful conference getting an automatic bid every year.
