If the Lady Vols lose to Ole Miss and Bama upsets Missouri, TN would drop into an 11th seed in the SEC Tourney and have to play the extra day. The best they can do is if they win and LSU loses which would make them an 8 seed.
The top three seeds are set (Miss St, South Carolina, and A&M. But if Georgia beats Kentucky and Missouri beats Alabama, and Miss St beats SC, Kentucky would fall to a 6 seed and Missouri would get the by. Or, in that scenario if Mizzou loses to Bama, Georgia would get the 4 seed. (Charlie Creme thinks Georgia has no chance at an NCAA bid, but a win over A&M and a couple of Tourney wins could change that. Georgia getting a bid might mean that TN's bid would have to be the 9th bid for the Conference -- not sure that would happen.)
TN fans should probably root for A&M, Mizzou, Auburn and Kentucky tomorrow.
