You are projected an 8 seed in the tourney, which means Lunardi is ranking you around #30 or so in the country. I put you a little higher right now, at around 20- 25th and so I would make you a #6 seed. I like UT MORE than bracketology does right now, not less.
You need to go .500 in the SEC and I don't think it will be that tough. Realistically, in the East there is one real good team right now (Florida), one good team that could get better over time (Kentucky), and then a handful of inconsistent but talented and promising teams, like you and Georgia. The West is really just a bunch of inconsistent teams that always could give anyone a game, especially at home, but realistically over the course of a whole season I see Tennessee rising to the #3 spot in the SEC East, and the #4 or #5 overall and thereofre in the NCAA tournament.
