Purdue and Iowa State picked up huge, resume building wins on Saturday in what was a very busy day.
The Boilermakers got their biggest win of the season at Michigan. The win for Purdue is just its second over a team that is sure to make the tournament. It was Michigan's first loss at home all season.
Iowa State picked up its first away-from-home win of any significance when it completed the season sweep of Kansas State. The Cyclones now have four top 100 RPI wins (despite a gaudy 11-5 conference record), and should be safe if they can get one more. Teams with just four top 100 wins have received 13 at-large bids in the last 18 years, but that's out of 250 teams.
It was a tough day to be a conference leader. Temple, Harvard, New Mexico, Long Island, and Middle Tennessee all lost. Duke, Syracuse, Kansas, Belmont, Drexel, Murray State, Oral Roberts, Nevada and St. Mary's all were pushed to the brink.
Alabama put another nail into Mississippi State's coffin with a win in Tuscaloosa. The Bulldogs have lost five straight and travel to South Carolina next. They are only 2-6 on the road.
Northwestern kept its hopes alive with a one-point win at Penn State. The Wildcats don't have many good wins (just six top 100), but none of their 11 losses have come to non-contenders. They have a chance to make a statement next when Ohio State visits.
Saint Louis took its worst loss of the season at Rhode Island on Saturday. For a team with few good wins, that's not a good sign. Also in the A-10, Saint Joseph's played their way back onto the bubble with a win over Temple.
Notre Dame lost at St. John's, which is the fourth bad loss of the season for the Irish. It's also the first loss of any kind since January 16th.
Kansas clinched at least a tie for the Big 12 title with an overtime win over Missouri. The Jayhawks are continuing their push for a No. 1 seed.
St. Mary's won the West Coast title outright, ending an 11-year streak during which Gonzaga either won or shared the regular season title.
Mostly irrelevant fact of the day: The Ivy League has half its teams in the top 100 of the RPI. Conference USA, the Colonial, Missouri Valley, Pac-12 and West Coast conferences can't say that.
The bubble watch will be updated this morning.
