The NCAA tournament is underway, and if you think you have the winning bracket - think again. If you haven't consulted KenPom.com, you're probably wrong.

Since 2003, Ken Pomeroy has been predicting winners of the NCAA tournament on his website, and his method is pretty incredible. Instead of a game by game statistics, he does it on a possession by possession basis. He also keeps track of the type of defense a team plays, and how an offense would fair against it. That's how he picks his winner.

Pomeroy uses math and science to make his picks, so while the majority of the country is selecting Louisville, Indiana or Kansas to win it all, Pomeroy says go with Florida - this year. If you're doubting his credibility, Pomeroy has written for the New York Times, ESPN.com and Sports Illustrated.
