One of the selection committee's main mantras is "Conferences don't get bids," but what's going on in the Mountain West and Atlantic 10 is very bad news for potential bubble teams from other leagues.
The Mountain West is the No. 2 conference in RPI, and for the most part, the top teams have beaten up on each other with almost all of the games going to the home team. This has created a scenario where teams are reinforcing each other and it seems a virtual certainty that the league will get four teams into the NCAA tournament. Even more concerning to bubble treams is Boise State, which still has several more opportunities for big wins (with three of its last four games at home). Thanks to the overall strength of the league, the Broncos still have a serious chance of playing their way in. They're a First Four team in today's new bracket.
What's worse for traditional power-conference bubblers is similar action is starting to unfold in the Atlantic 10. The top of the league is playing a quasi-round robin down the homestretch of the season, and teams like Saint Louis and Temple are picking up valuable wins to help their profile. This league also looks pretty likely to get four teams into the NCAAs, with five not an unreasonable ask at this point.
