college football.
Blow away all the current conferences, blow away all the bowl games, blow away all the history, blow away all the old rivalries, etc.
And restart all of it any a way that makes sense. We worry too much about blending the past with current needs. The bowl system and a playoff don't fit well together.
Stanford and Cal don't belong in the ACC. USC/UCLA don't belong in the B10. WV doesn't belong in the B12.
Snap your fingers and make some conferences that make geographic, economic, and rivalry sense. Create a manageable post season that gives a chance to deserving teams and crowns a true champion.
