Someone has to win the games, though you're definitely putting yourself in a precarious position. Even though you've been ranked for most of conference play, you're not yet a lock for the dance by any means.
4 of your last 6 are on the road, though 2 of those are Auburn and South Carolina. One of your two home games is UK.
If you go 3-3, I think you're in the dance at 22-9 (9-7) with likely a mid-30s/high 40s RPI. If you go 2-4 the rest of the way, you may need a win or two in the SEC tourney depending on the rest of the shake up.
Like I said though, even if you crap the bed and end up in the NIT, it's gonig to come at the expense of someone. Alabama would probably boost their way in, or Arkansas. The SEC will get 4 at an absolute minimum, not because the committee wants it that way, but because there will be enough decent resumes to make it so.
However, I don't think it's ridiculous to proclaim that the SEC will likely only have one team advance past the first weekend (Kentucky), which would make it just like a lot of other years in the history of the SEC. Kentucky and not much else.
