As others have somewhat mentioned, nothing will come of this precisely because the SEC doesn't need the NCAA. But the NCAA needs the SEC.
Would the fans paying billions of dollars to see college kids play give a damn what "non-profit" body sits behind their football. Of course not!
And the NCAA is not at all willing to give up on their giant masses of money, hell no.
The NCAA is going to either do nothing, or if the noise from other non-SEC institutions gets too loud, do as little as possible so as to not **** off the money tree that is SEC football but still placate the masses.
