According to the Washington Post, " . . . the last time the four No. 5 seeds went 4-0 in the NCAA tournament's first round was 2007 (a true aberration: they won by an average of 16.3 points). Since then, being a No. 5 seed has been something of a hex.
In 2008, there were two 12-5 upsets. The next year, there were three. And over the past three tournaments, No. 12 seeds have gone 8-4 against No. 5 seeds, with six of them pulling off upsets in 2013 and 2014 combined."
