1) Every conference should have 2 divisions, and a title game = 1st round of playoff. This means independents have to join a conference or get left out.
2) Keep the bowl system intact, only have 6 bowls set aside for the conference championship winners. Non conference winners play in the rest of the bowls.
3) Don't put out a BCS until after the bowls are played, and whoever is #1 & #2 play in a +1 National Championship Game.
This is the closest way to making everyone happy that I can think of, but it still has problems.
It's not a true playoff in the truest sense of the word playoff.
Notre Dame is bigger than the rest of college football, and will never join the Big East in football like they should. Same for BYU and the rest.
BUT, we could keep the bowl system (tradition and $), keep the BCS (makes every game every week important) and have an almost playoff.
Without a real playoff that scraps the bowl system, and implements more games than school administration will allow, this is as good as it could get, IMO.
But, just like politics, nobody asks me what I think we should do.
