The NCAA basketball tournament is unlike any other in sports – a one-and-done white knuckle ride to a national championship that results in the kind of democratic process rarely seen in the sports arena. In a best-of-7 series, the better team usually finds a way to win, either through sheer talent or home-field advantage. In a single-elimination showdown played on a neutral floor, anything is possible. That's why the underdogs make this tournament so compelling.
"Cinderella stories are what you remember from a tournament," says Rob Dauster, lead writer for NBC Sports' College Basketball Talk. "The upsets – cheering for an underdog – are always exciting and fun, and correctly picking an upset in your bracket is what the NCAA tournament is all about. But the story behind the Cinderella is what makes those upsets memorable." While we wait for the first 16 seed to spring the ultimate upset, here are the 13 teams who have etched their names in the annals of March Madness by bucking the odds.
Defending national champ UCLA was ready to make run as the No. 4 seed, but their dreams of back-to-back would be denied by the 13th-seeded Tigers, who finally tallied an upset. The Tigers had experienced tough losses to Georgetown, Arkansas, Syracuse, and Villanova in prior tournaments, but this time, their precise offense was enough in a 43-41 win.
