Having four sixteen-team "supersonferences" sounds good, but how do the other 60 FBS schools get structured? They have to have a realistin shot at the title or anti-trust problems present themselves.
I am becoming more and more in favor of some sort of relegation system where the structure of. 16 team conferences is fluid. Two Eight-team conferences per conferences, so seven division games, three or four OOC games that can be scheduled in advance to maintain traditional rivalries. Add a conference championship and then a 4 team playoff. This effectively makes it an eight team playoff and the national championship plays 14 games. Lesser teams play 11 games. Lowest finishing teams are relegated to the divivion of 60 to have a shot at winning their way back into the division of 64. The downsides to this are it anhilates traditional conferences, makes scheduling a mess done less than a year in advance and means a lot more travel to places teams may never have played before.
