NASHVILLE—-Turns out that when you win, things start to take care of themselves. Vanderbilt’s RPI sits at No. 68 following its 12-6 Tuesday night win over Louisville that gave it back the bragging rights in the Battle of the Barrel. Vanderbilt moved up three spots as a result of its Tuesday-night win.  That RPI would all but disqualify it from the NCAA Tournament if it were to start today despite the Commodores’ Tuesday win, but it’s progress. The highest RPI team that got an at-large that I can find was TCU at 59th in the RPI in 2019. However, TCU won two games and made a run in the semis of the Big 12 tournament that year. Vanderbilt will likely have to make a similar push to get its RPI to that point. Perhaps it doesn’t have to get it all the way there, but it’s got to be nearly perfect the rest of the way to get it close.  Only seven guaranteed games remain for Vanderbilt; three on the road against Missouri, three against South Carolina and at least one at the SEC Tournament in Hoover.…
