One of the biggest reasons for interest in the NCAA men's basketball tournament is the anticipation and expectation for upsets to happen. Every year college basketball fans fill out their brackets and try to predict the crapshoot of all of crapshoots in sports. Nearly all of them are left dumbfounded year after year, when a school few have ever heard of before upsets a well-known school in the early rounds of the tournament. Sometimes it isn't quite midnight for Cinderella after just one upset. It's not too uncommon to find a double-digit seed in the Sweet 16.
Everyone seems to have experienced the loss of a Final Four (or two or three) on the first weekend of the tournament and some really unlucky people have even lost their title pick on the first day of the Big Dance. Upsets have helped put little-known programs in the national spotlight and are usually a bigger story than the title contenders. Sometimes it's easier to recall the upsets and the bracket buster from a particular year than the school you picked to cut down the nets. Bracket Busters and Cinderella teams are what March Madness is all about.
