The revolving door at the top of the bracket continues

Three of the top seeds in Monday's bracket lost this week, and two of them have been replaced in Friday's version. Indiana remains the overall top seed, but Duke and Michigan fell off and were replaced by Georgetown and Michigan State.

Indiana lost to Minnesota, which desperately needed the win to stop a monthlong slide. It's the second time this year the Hoosiers lost to a team in that situation. Illinois got off to a 2-7 start in league play before beating IU.

Duke lost Thursday night at Virginia, their second loss to a team outside the top 50 since Ryan Kelly got hurt. For now, that knocks the Blue Devils down to a 2-seed. Virginia has been added to the bubble and is among the first four out of the bracket.

Michigan lost to Penn State, which was 0-14 in conference play and had lost 18 straight Big Ten games going back to last year. The Wolverines have now lost four straight on the road and, given their remaining schedule, could be in danger of an even bigger fall.

There was turnover at the bottom of the bracket as well. Tennessee, which beat Florida and Kentucky move in, replacing Charlotte and UMass.
