In fairness, wins over the RPI top 50 and/or over other at-large teams are generally considered quality wins. Tennessee has wins at Oregon State (#7 RPI), over Syracuse (#17, currently projected as a 4-seed), and at Missouri (#29, projected 6-seed). Chattanooga (#50) and Albany (#51) are borderline top-50 wins, but neither would be likely to get an at-large bid (currently projected as 13-seeds). Auburn, though only 60-ish in the RPI, is a bubble team.
That makes one excellent win, two solid quality wins, and three kinda good wins. Of course those are counterbalanced by the four losses to teams outside the RPI top 100.
Yup.
And a bunch of their losses are 'good' losses - losses to teams clearly getting into the tournament.
And this is not all being determined in a vacuum either - it all ends up being 'relative' to the other teams at the back end of the at large pool and what their quality wins, quality losses, and bad losses are.
There are 31 at large bids and of those probably the first 25 are pretty obvious - the runners up in a few mid majors (say 3) plus the runners up in the BE and AAC, plus the top 3-4 teams in the P5 conferences that don't win their respective tournaments (say 20 teams)
So that leaves maybe 6 remaining spots that are really debatable among maybe ten teams and none of those ten teams has an unassailable resume - they don't have many if any quality wins against teams already selected for the tournament let alone against ranked teams, and they mostly all have some pretty bad losses. Within that universe even if they lose their last two games TN stands out as having played a lot of 'quality' teams that are already in the tournament and having a few quality wins. Even at 16-14 stacked up against teams with much better records, the quality of those records doesn't bear close scrutiny.
I think a 16-14 TN team would get in, but it would be borderline, a 17-13 team or a 18-13 team which are quite possible is probably assured of getting in. They are a bad team playing terrible basketball with no change in sight, but the evaluation process strongly favors them. I would much rather see a good mid-major get a shot than to see TN stumble into the tournament - but the committee has almost never done that so i don't expect it to this year.
