My only analogy / comparable is college hockey, first with the ECAC / Hockey East split then with WCHA /NCHC /B1G splits. While the top-tier selective conferences (HE/NCHC) ended up with more tournament invites, the less intense, non-scholarship, smaller school conferences (ECAC / WCHA) ended up with several national championships and Frozen Four teams. Football of course is bigger time, but if you split off the secondary teams of the B1G and SEC, add in some of the ACC, you could get entertaining football, and as long as the conference champs got invites into an 8+ team tournament, they'd get the occasional hot run. Why not let SC, Vandy, maybe Miss St, GA Tech, Tex A&M form what is essentially a little SEC for football and get back to a 6 or 8 conference set up for the FBS? more good TV games to stream this way, a bigger playoff for the bowls, etc...
