re: Alabama/UGA/Auburn/Tennessee Fans...lets say we did away with your games...

I still imagine a 16 league with four divisions in the near future. Perhaps it is counter-intuitive but I think that might be the best shot at keeping more of the core rivalries intact. Imagine something like:

Southwest:
LSU (Florida)
Arkansas (Virginia Tech)
A&M (Missouri)
Ole Miss (MSU)

Northwest:
Bama (Tenn)
Auburn (Georgia)
Missouri (A&M)
MSU (Ole Miss)

Northeast:
Tennessee (Alabama)
Virginia Tech (Arkansas)
NC State/ECU (South Carolina)
Vanderbilt (Kentucky)

Southeast:
Florida (LSU)
Georgia (Auburn)
South Carolina (NC State)
Kentucky (Vanderbilt)

This would imply a 8 game conference schedule with four fixed opponents (the fixed out of division opponent is noted) and allow you to rotate four new opponents every two years. And the whole premise would hinge on your ability to have a two round division playoff to settle who wins the SEC (I like the idea of them being seeded and the top two seeds hosting the first round)

It isn't perfect. I would hate seeing fewer games between LSU and Bama/Auburn. But considering the other options something like this may turn out to be the best available solution.
