The way I'm looking at it, according strictly to RPI and nothing else, we're four spots ahead of the cut line with 3-4 potential "steals" left.
Tomorrow, we'll want:
Dayton over Saint Louis
Vermont over Bryant
Charlotte over FIU
Penn over Princeton (If Princeton lose, we'd also likely jump them in the RPI and be 5 spots ahead of the cut line.)
So things are looking good, but for some extra comfort, we could use the games above going the right way.
