re: If the SEC does expand, it appears it will be in the east...

8x2 just means you have eight-team divisions. Basically it'd be moving Missouri to the West (where they belong) and adding the two North Carolina schools to the East, to make two eight-team divisions. After that each one needs a permanent rival to preserve some of the big rivalries (Alabama/Tennessee, Auburn/Georgia, etc.), so I reassigned permanent rivals with that in mind.
