Do you need to quantify what happened on Friday, March 16, 2012, in the NCAA tournament? Because there are ways. You could say that only four No. 15 seeds had previously beaten No. 2s, the last occurrence coming 4,019 days ago — and then it happened twice in less than three hours, with Norfolk State, champions of the MEAC, unleashing a plague of threes on Missouri, and Lehigh, champions of the Patriot League, methodically dismantling Duke. You could say that the chances of those two upsets happening, according to kenpom.com’s projections, was 0.72 percent, and if you add in No. 14 Ohio’s ousting of Michigan, that drops to 0.21 percent. Two-tenths of one percent! You could say that $100 parlay bet of Norfolk State, Lehigh and Ohio would pay out around $100,000 in Vegas, or that it’s the first time in tournament history that three teams seeded No. 13 or lower won on the same day.
