This is my pipedream for the NCCA and the current changes: 4 Super Conferences.
In a perfect world, you end up with the 4 Super Conferences and do away with the BCS and have a legitimate playoff system intact for your National Championship.
You already use a tournament-style post season for basketball, baseball, hockey, etc. so the conference realignment doesn't negatively affect that.
Of course, this is a long way off and the BCS is a goldmine for TV revenue. But I can dream.

Hail kings. The new kings. Stronger Than All.
