This is a bit off-topic, but I think the conferences are getting too big. I don't think any conference should have more than eight teams. You have built-in inequity when all of the members of a conference don't play each other. Also, some of the conferences are becoming geographically dispersed in a way that's ridiculous.
It all comes down to money, if your conference has 12 teams, you get a championship game = more money!
