10. 15 Seeds Lehigh and Norfolk St. Both Reach 2nd Round (2012)
As we mentioned before, only six 15-seeds have ever made it past the first round of the NCAA Tournament. Two of those teams accomplished the feat on the same day last season—the first time that had ever happened, as you might expect. Both games were engaging down to the wire, as Lehigh stunned Duke with its first-ever tournament win, 75-70, while Norfolk State took care of Missouri by a count of 86-84. Lehigh’s C.J. McCollum put on a show, running up 30 points, seven rebounds and six assists, while Norfolk State was led by Kyle O’Quinn, who posted 26 points and 14 rebounds. These teams probably ruined your bracket last year, but if you truly love March Madness, you still enjoyed every minute of it.
