2023 March Madness Round of 64 Betting Predictions: 1st Half Unders?

Since 2011, there has been a trend that has left sharps incredibly profitable.

Over the past decade-plus, first-half unders have won about 60% of the time during the Round of 64 and First Four.

When expanding the scope to the entire tournament, first-half unders win about 58% of the time.

Let's get more granular with this, though.

First-half unders for games that start at 2 p.m. ET or earlier have gone under 66% of the time when the total is fewer than 70 points. That's an eye-popping 25% ROI since 2011. A $500 per game bettor would be up about $11,250.

For the Round of 64, here are the games with a requisite first-half total under 70 and that tip off before 2 p.m. ET. Listed is also the best market price and which sportsbook is providing it.
