Bettors and fans paying close attention to the 2023 NCAA Tournament Round of 64 may have noticed a glaring betting trend — and it has nothing to do with Cinderella upsets.

Rather, betting unders in the NCAA Tournament produced one of the largest edges we've ever tracked during March Madness.

2023 NCAA Tournament Over/Unders

NCAA Tournament Round of 64 games were 27-9 to the under. At a 75% clip, it's the best win percentage for tourney unders in the last 30 years, according to our own Director of Research Evan Abrams.

Friday was nearly a clean sweep. The first seven games of the day went under the closing betting total, as did seven of the final nine thereafter.

Some of the games don't even feel close.

Iowa State, for example, had trouble topping 40 points.

It was the lowest point total of the year for the Cyclones, who actually experienced a pregame issue with the rims, potentially aiding in the low-scoring rock fight on Friday.

Thursday's Princeton-Arizona (59-55) total, meanwhile, closed at 153.5. The 39.5-point difference between final and close is one of the largest in NCAA Tournament history.

Furman and San Diego State meet early in Saturday's Round of 32, with an over/under of 135.5.

Let's check out the other over/unders for Saturday's NCAA Tournament (via FanDuel).
