UConn is 16-11 with an RPI of 76. If UConn won 6 in a row and got to the AAC finals, their RPI would probably jump to about 50 since the Huskies would pick up some quality wins along the way. Other teams between 40 and 90 in the RPI are most likely going to keep picking up losses so it is not that hard mathematically to make a big jump if a team keeps winning. If UConn was 22-12 with a 50 RPI and a handful of quality wins on Selection Sunday, UConn probably gets a bid. To provide some perspective, there are probably about 30 teams that could play themselves onto the bubble with a 6 game winning streak right now.
The bigger problem UConn, and all those teams, face is that any team that needs a 6 game winning streak at this point in the season to get a tournament bid is probably not that good to begin with.
