There seems to be a lot of sentiment that an 18 or 20 team superconference is "too big"? With that size you can't play everyone in your conference, but you can play everyone in your division and then meet the other division winner in the superconference championship. So, basically, you have 2 conferences with a formal arrangment to play a championship game and share marketing arrangements (notably, TV revenues).
I see no problem with this. Let the Big East and Big 10 merge (with Penn State moving back east). Let the Pac10 join with some combination of the WAC and Mountain West. Let the ACC and SEC trim a few and join up. Let the Big 12 pick up teams who got lost in the shuffle and/or midmajors.
In the end, the conference championship games will serve as the first round of an 8-team playoff. ..The top 4 remaing play each other on New Years day. The national championship is about 2 weeks later.
It doesn't address fairness for non-superconference teams, but its a major step forward, without killing off intrenched interests.
