A true 16-team FBS playoff with the champions of all conferences getting an automatic bid, filling the balance with at-large teams, higher seed hosts until the championship game held at a neutral site and conducted completely outside the bowl structure would leave us arguing over who should have gotten an at-large bid.
Kanasa State of course would have represented the Big XII. Would TCU have gotten a bid "competing" against Ohio State, Alabama, Tennessee, etc?
But I imagine we would all be more interested in a playoff game between Clemron and Tennessee in either Neyland or Dung Valley rather than neutral Miami.
