Here is my idea, but I doubt it will happen. For FOOTBALL only, go back to 1A and 1AA. And, since there are so many schools switching conferences, have what is now FBS/1A determine a set number of schools that will play at that level. The growing trend with the BCS Conferences is moving to 12-14 teams. Also, the non AQ Mountain West will be at 12 schools for football starting this fall, with the addition of Utah State and San Jose State. Hawaii is a member for football only, and the WAC will no longer have football starting this season. Not really sure if the Big East is deserving any more of being deemed a "BCS" Conference?
I think a good number might be 100-105 schools in this division? Go with the current BCS Conferences and Notre Dame, plus MWC and CUSA. Then take the best teams from the MAC and Sun Belt(although many Sun Belt teams are now moving to C-USA), and create a football only conference. BYU and ND can remain Independents. And, due to tradition, also keep Army and Navy in 1A.
The schools that do not make the cut, drop down to 1AA.
This would make 1AA a much higher quality of football. It gets rid of the perennial bottom feeders in 1A, that lose large sums of money. This solution would likely require the formation of at least 1-2 football only conferences in 1A. Could be a combination of schools from MAC, C-USA and a few from The Sun Belt.
Then, go back to 1A and 1AA for the names.
There are currently 124 teams in 1A/FBS, with GSU, Appy State and maybe a few more set to join. The vast majority of these schools have little shot at playing in a BCS Bowl, the soon to be FBS/1A playoffs or one of the remaining prominent bowl games?
Any thoughts on this idea?
