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.
