The calendar has turned to March, which means the madness is here once again — if it hadn't started already.

Here are four teams that could make a surprising run to the Final Four (results/records are through Wednesday).

► Butler (23-6, 12-5 Big East): This team beat Villanova twice and is as dangerous as it gets when it comes to a No. 3 or No. 4 seed. Kelan Martin (16.0 ppg, 5.8 rpg) paces this veteran team under coach Chris Holtmann.

► Florida (23-6, 13-3 SEC): Coach Michael White has gotten Florida back to an elite status and near the top of the SEC, yet Florida isn't exactly a team on anyone's radar to go to Phoenix, especially with big man John Egbunu out for the season. But the ingredients are still there for a team that had won nine in a row before falling at Kentucky last weekend after previously hammering the Wildcats by 22 points at the beginning of the month.

► Iowa State (20-9, 12-5 Big 12): Iowa State has beaten Baylor and Kansas and subtly surged to second place in the Big 12 standings. Not bad for a team that was on the bubble not too long ago. Coach Steve Prohm has the Cyclones rolling, winning five in a row, which feels like it should count for more in the Big 12. Senior point guard Monte Morris (16.3 ppg, 6.0 apg) gives this team a chance to win against anybody.

► Dayton Flyers (14-2, 23-5 A-10): The residue of the Flyers' Elite Eight run in 2014 remains on the roster with mainstays Kendall Pollard and Scoochie Smith, but perhaps the main reason Dayton is a team no one should want to face in the bracket is Archie Miller, who continues to keep this team atop the Atlantic 10. The Flyers wins games on the defensive end, and play with a noticeable chip on their shoulder.
