It was actually pretty quiet at the top of the bracket, but the bottom is really falling out and now teams who just win are moving ever higher in the bracket.
I've got George Mason up to an 8 seed after a dominating win over Old Dominion on Saturday. That win is their only win against a top 50 team but they've won 9 in a row and will probably make it 10 before challenging games against James Madison and VCU. 7 seeds Utah State and St. Mary's are having an easy time against their Western opponents so it's a good thing they're facing each other in the ESPN Bracket Busters in a couple of weeks.
On the other end of the scale, Michigan State has lost 5 of their last 6 including an embarrassing 26-point loss to Wisconsin on Sunday. Some brackets have them out and even though I've still got them at an 11 seed, it'll be hard even to keep that position. Much improved Penn State is coming up followed by OSU, Illinois, Minnesota, and Purdue.
