Whether it's Texas or A&M, I think Georgia wins the SEC CG. They'll get one of the byes. If A&M beats Texas next week, Texas takes a big hit. The championship games will have a lot to say about where teams are seeded.
Ideal scenario:
Beat Vandy
Texas beats A&M
Texas beats UGA in SECC game
We finish 3rd in the SEC, rest up, be the best 2-loss SEC team, and likely host.
