It's hard to overstate what a feat it was for the Bulldogs to make the national championship game in back-to-back seasons. Both times, they had an inexperienced coach and a roster filled with workaday players. Still, Butler did just that, coming one rim-bouncing 3-point shot away from earning the greatest title upset of all-time against Duke in 2010, and using a miraculous win over Pittsburgh in the Round of 32 to spark another championship run in 2011.
