Have the ditched the quads idea?
In a 4 division conference, the logical split would be
Georgia, Florida, USC, UK
UT, Vandy, Bama, Auburn
Arky, LSU, Miss, Miss State
Okie, UT, TAMU, Mizzou
This saves most of the rivalries and has geographical sense as well, plus being somewhat balanced in power.
If they aren't having Quads, what are they having? Two divisions of 8 each, where you only play 5 of the 8 teams in your division each year? Or one single conference, where you play 9 of 15 other teams and the top 2 records play for the conference title, or maybe they get rid of the SECCG entirely?
Only the quad system makes sense, as you would play everybody who you are in competition against for the league title. Yes, it means a 4 team SECCG, which is not optimal. But it's still better than having a situation where you are by far the best team in your division but lose the division title because a team you didn't even get to play had a far easier schedule than yours, or worse, you both went undefeated in the division but they won on some tiebreaker. Which would be horrible. Unless it happened to UGa, then it would be hilarious.
