I'm interested to see what the SEC does in respect to alignment. Will they go with a geographic split, which would be much easier to do with UT and OU? Or will they try to "balance" the divisions in some way? If they went by geography, I'd imagine it would be something like this (end of year rivals pair together):

SEC West:

Texas / Texas A&M (Texas & Oklahoma play mid year as usual)
OU / Missouri
LSU/ Arkansas
Ole Miss / Mississipi State

SEC East:

Alabama / Auburn
Tennessee / Vanderbilt
South Carolina / Kentucky
Georgia / Florida

To me, that seems like the best way to do it.
