IMO the cadillac model is a 16 team playoff like the FCS does it. Have the champions from the major conferences with the rest made up of "wild card" teams (high ranked teams that don't win their conferences). Would be one heck of a playoff. I really enjoy watching the FCS playoff, there are some really good games. You could use some of the bowl games for playoff sites and the teams that didn't make the playoffs could top off the bowls.
