Just to get a feel for example best case and worse case scenarios w/respect to RPI (all other things being equal) ...
A tourney sweep with (1) win over South Alabama, (2) wins over James Madison, and (1) win over Southern Mississippi would yield an RPI that is ranked #25 in the current RPI rankings.
(2) Tournament losses to Old Dominion would yield an RPI that is ranked #44 in the current RPI rankings.
But keep in mind that much still depends on what opponents do as well as teams ranked around the Cajuns. As such, the results can vary by a few spots.
BTW, I can see some of the outfield, the left field wall, and center field wall from our hotel room. The downtown area is nice with plenty of eateries and places to grab drinks.
