After 52 games, the field of 68 teams in the 2013 NCAA Tournament has been narrowed to 16.

In a typically mad stretch of March, the unheralded Eagles of Florida Gulf Coast University earned a spot in this select group while the team atop the AP poll on Selection Sunday did not. Top-seeded Gonzaga was ousted in the third round by No. 9 Wichita State in the wild West Region. In that same section of your very likely busted bracket, No. 15 Florida Gulf Coast ousted both No. 2 Georgetown and No. 7 San Diego State.

The East Region went a bit more predictably, sending its top four seeds into the round of 16. In the Midwest, No. 1 overall seed Louisville overwhelmed its first two opponents, doing nothing to disappoint the many experts who tapped them to cut down the nets in Atlanta.

With three double-digit seeds remaining and three No. 1 seeds, the action picks up on Thursday, March 28 at 7:15 p.m. EST when No. 2 Miami and No. 3 Marquette tip off in Washington, D.C. in the East Region.
