The best the bracket has so far is a pair of No. 12 seeds over 5s. That's become almost expected — occurring at 35% clip, according to the NCAA — and one of them wasn't even an upset. Colorado State was favored by 2 1/2 points over short-handed Memphis, according to BetMGM Sportsbook, and the Rams won 78-70.

The first round of the NCAA Tournament brought a few surprises, but compared to the recent three-year streak of 15-seeds advancing, or two 16-seeds winning in a span of six years, it was remarkably light on true upsets.
