Everybody thinks that SDSU belongs as a top level program except the fans who pay for it. They are in a large and fast growing city without competition from the NFL (or the NBA, NHL, etc.) but they still don't draw and they don't generate TV ratings.
For right now I think the best course of action would be for the best programs from the remaining three conferences PAC, B12, ACC to form an entirely new conference of the top say 16 programs, sign them to strong GOR agreements, and dump the rest of the programs which would be a drag on the conference. From the PAC that would mean OSU and WSU gone as well as likely Cal. B12 schools that wouldn't be included would be some of their recent additions, ACC has some programs that don't make the cut as well. Depending on what the TV networks want you may go as high as 24.
And again long term it isn't going to matter because college football as we know it is already dead, they just haven't realized it yet. There will be a tier of schools that forget all pretense of being college athletic programs and spend and receive huge amounts of money. Eventually a bunch of schools are going to recognize that they aren't included and that they don't want to be and we see a new, lower budget structure evolve.
We may, and probably eventually will see the NFL decide they want those billions and take over the top level talent development under their own minor or developmental league cutting the colleges out of the money and process.
