Murray St's best win, Memphis, has 6 losses and is #28 in the RPI. Next best win is Southern Miss at #63 and Dayton at #70 in the RPI. And after that, the wins are not just bad, but horrendous.
Murray St themselves are #117 in the RPI and will not finish higher than 100 due to the league they play in.
If they go undefeated, they cap out at 4 seed.
