Upsets provide the madness for March Madness. Shocking early-round results are almost inevitable, and they make the NCAA tournament the fascinating event it has become.
Three times in the past two NCAA tournaments a No. 15 seed has taken out a No. 2 seed: Lehigh beat Duke and Norfolk State eliminated Missouri in 2012, and and Florida Gulf Coast knocked out Georgetown last year. A No. 14 seed, Harvard, ousted No. 3-seeded New Mexico last year as well.
The opportunity for a little-known college to eliminate a powerhouse begins on Thursday's Day 3 of the tournament, when the frenetic round of 64 gets underway.
This year, the prospects are better than ever that high seeds will crash in their first games. Seven teams look vulnerable in their opening games on Day 3, putting them on Upset Alert.
