March Madness odds and picks: UNC vs. San Diego State, St. Francis vs. Alabama State

Here are odds for the first two games of the 2025 NCAA Tournament:

• Alabama State (-3.5, 139.5) vs. St. Francis
• San Diego State vs. North Carolina (-4.5, 142.5)  

UNC vs. San Diego State pick

The Tar Heels are getting a lot of negative attention, with many saying they didn't deserve to make the NCAA Tournament. They will quiet the haters, though, by winning at least one game and possibly even making a little run as they got a favorable draw. The Tar Heels have the pieces they need, with an elite scoring guard in RJ Davis averaging 17 points per game. He has some talented young guys around him, too, with freshmen like Drake Powell and Ian Jackson coming on strong to end the season.

Alabama State vs. St. Francis pick

St. Francis has made a miraculous run to the NCAA Tournament after winning the Northeast Conference Tournament. The Red Flash came in with a 13-17 record but found a way to win three straight to earn an NCAA Tournament bid. Alabama State has a better overall record but had a similar position coming into the Southwestern Athletic Conference Tournament as the fourth seed and made a run to win the whole thing. This matchup comes down to who can make tough shots, and Alabama State has that guy in CJ Hines. Hines is coming off 20, 15, and 15 points in his last three games, and we expect his hot scoring run to continue leading the Hornets to the win on Tuesday.
