UT beat us head to head so they have the tiebreaker on us if it is just the two of us tied. However they go to Vandy one night this week, and I doubt they win in Nashville. If we both win out and finish 8-10 that means Ole Miss would also be 8-10 since we both play them this week, but with four other teams also sitting at 8-8, the possibility of a four or five way tie is pretty good.
While I like the prestige of the higher seed, in reality it doesn't matter a lot for us. So with that I'm thinking the 11 spot looks pretty good. Open with the six seed which will most likely be the 8-8 team who wins twice this week (Bama? Georgia?), then the 3 (USC again?), then TAMU and Kentucky in some order on Saturday and Sunday. It will at least be decipherable after the midweek games but like you said there are way too many possibilities and tiebreakers to consider at this point.
