A look at Sunday's regional finals in the NCAA Tournament:

4. Michigan (29-7) vs. 3. Florida (29-7): Michigan advanced with a miraculous comeback over No. 1 Kansas Friday. Florida sort of plodded along and beat Florida Gulf Coast. Michigan has the most impressive victory in the tournament too, a vaporizing of VCU. The Michigan guards, Trey Burke and Tim Hardaway Jr., are speedy, smart and dangerous shooters. Florida’s guards, especially Mike Rosario, can match them for the most part. Neither team has a great inside game so it will come down to whose guards gain the advantage. Right now, Michigan’s are playing better.

Louisville (32-5) vs. Duke (30-5): Louisville hasn’t been tested in beating North Carolina A&T, Colorado State and Oregon. The Cardinals full-court press and pell-mell style has set the tone in those three victories. Duke will not be pushed around so easily, the Blue Devils will match any physical play. They also will not be intimidated by the full-court pressure. That doesn’t mean they’re going to win. This will be competitive, maybe even close but Louisville has played like an overall No. 1 seed should. Right now, they’re the best team in the tournament.
