OK, which scenario do you favor:
1) The current proliferation of lower tier bowls, most of them being in desireable vacation spots.
2) A new post season tournament for those non BCS conferences which are in between the the old nomenclature of I-A and I-AA. The MAC, Sun Belt, Conference USA, and maybe the top two or three current I-AA conferences would place either four or eight teams in a bracket and play for a national title. Higher seeded teams could host all the way through, or else the games could be held in current lower tier bowl sites.
Option #1. The second option doesn't make any sense. The schools in the MAC, SBC, CUSA are not interested in moving down and schools in the Big Sky, MVC, Colonial are hesitant as it is to move up. They aren't going to move up to be in a subdivision with only the MAC, SBC and CUSA. I have never heard of FCS conferences disliking the playoff system they have going and wanting to get rid of the smaller FCS leagues. There are a lot of very good academic institutions in the FCS ranks that a Northern Iowa would want to be aligned with. Better off letting Ohio move down to the MVC and getting the side benefit of an improved basketball conference.
