This is just inaccurate and has no merit behind it.

****************************
Tennessee definitely has bad losses, especially when you factor in RPI, but they also have better wins than most bubble teams, especially if teams like Auburn, Belmont and LSU hold their spots and make the tournament. When looking at Cal vs. Tennessee and analyzing who is a better team, I think it's pretty clear that Tennessee has an edge at this point and is more deserving of a spot. And this is coming from someone who doesn't want Tennessee to make the tournament
If Tennessee loses to either Vandy (200 RPI) or Ole Miss (201 RPI), that'll be a horrible loss that pushes them on the outside of the bubble. I honestly don't see Tennessee losing either of those games, but anything is possible with Holly.
As long as they beat those teams and lose to SC, they'll likely be the #7 seed in the SEC Tournament (have tiebreakers over LSU and Auburn) and will face Arkansas or Alabama for a spot in the quarterfinals. Tennessee wins that, they're in the tournament pretty safely. If they lose, they might be on the outside looking in depending on how other teams fare in their conference tournaments.
