NCAA Tournament Day 1 Live: Betting Trends, Results, Notes, Data & More article feature image

Welcome to March Madness! Let’s take some time to recap some of the wildness for Day 1 of the 2023 NCAA Tournament.

The day started with three underdogs winning outright with Furman, Maryland and Missouri.

Then, in the next set of games, back-to-back down to the second covers in Texas A&M Corpus-Christi and College of Charleston-San Diego State brought us into the night slate.

And finally, we just witnessed one of the biggest upsets in tourney history, with 15 seed Princeton knocking off Arizona.

Tennessee (58)

+ Tennessee escapes the Round of 64 against Louisiana-Lafayette, but unfortunately for their spread bettors, they failed to cover the number — a theme for Rick Barnes.

Tennessee wins, but doesn't cover.

+ Not to mention, this win gave San Diego State and the Mountain West their first win in the NCAA Tournament since 2018.

A VERY IMPORTANT FOUL 👀
