4: Duke over UNLV
In 1991, the Duke Blue Devils shocked the UNLV Runnin' Rebels, 79-77, in the Final Four. The upset was truly special because UNLV embarrassed Duke by 30 points in the national title game the season before, and entered this 1991 semifinal game with a perfect record. (AP File Photo)
