Well...if it is a matter of division, then UT has lost to only 1 SEC East team...where Georgia has lost to two. But....I think that everyone recognizes SEC losses as SEC losses....we each have two (as of now) ... but UGa lost to us. I don't see the "sharing" argument right now...but perhaps I can be convinced otherwise..
If you only look at East division loses Florida would win. They only have 1 division loss, and hold the tie-breaker over us.
And to your earlier question, if we beat Kentucky Saturday, Georgia and Tennessee will be co-champions of the East. Since only one team from the East can play in the Championship game, they use a tie-breaker, and Tennessee holds that over Georgia.
