We're getting to the stage where every win shifts the bubble.  Butler's win in the Horizon League championship game was great news to all the teams on the bubble as it "expanded" the field by one team (I was leaving open the possibility the Horizon League could get two bids had Butler failed to win).
Other notes:

• Villanova's epic collapse shouldn't cost them a spot in the tournament but they are no longer in "lock" territory.  It's likely they'll return in a couple of days after the bubble becomes more clear.
• The bubble is rooting for Utah St. and UAB to come away with conference championships.
• Harvard and Princeton play a winner-take-all game this Saturday for Ivy representation.
• If New Mexico were to beat BYU for a third time they would likely re-enter the bubble discussion.
• Baylor's bubble has nearly popped and Nebraska is now definitely out.
