Here's a thought exercise - not saying I think this will happen but fun to think about...
It's interesting to think about a schism of the SEC and then everyone else.
In that scenario, you could foresee some schools (likely east of Texas) that place ultimate importance on football join into the SEC (so, maybe they go up to 24-30 schools). This becomes NFL-lite and they put whatever weight on Olympic sports and academics that they want.
Then everyone else in the new NCAA ("NNCAA"); playing more regionally based schedules along the lines of the current P5 conferences, putting similar weight on Olympic sports and academics as they do now. In other words, like the current NCAA.
Two aspects:
1- as a sports fanatic, what percentage of your time/attention would you give to the two "bodies"?
Mine would be 10% SEC/90% NNCAA.
2- for non-fanatics, it seems like some casual fans would get caught up in the SEC championship game and some would get caught up in the games of good old State U vs. whoever they're playing.
I think the majority of America would be focused on the NNCAA.
So, in the end would the SEC just become another USFL with basketball and not much else in their AD's?
