2026 March Madness Schedule + Expert Picks
The Elite Eight wraps up on Sunday with these two high-stakes matchups. Register for a new account with BetMGM bonus code ACTIONGET to use this welcome offer on your top pick of the day.
Sunday, March 28
- Tennessee vs. Michigan at 2:15 p.m. ET on CBS
- Expert Pick: Michigan -3.5 1st Half (-110): Michigan dominated early in the season and, despite a few late losses and injury concerns, has cruised through the NCAA Tournament while consistently excelling in first halves. With a strong defensive presence and Tennessee dealing with matchup challenges and injuries, Michigan is well-positioned to cover the first-half spread.
- UConn vs. Duke at 5:05 p.m. ET on CBS
- Expert Pick: UConn ML (+180): UConn’s experience and Dan Hurley’s proven March coaching prowess give them an edge over Duke’s talented but young lineup. Despite Duke being the favorite, I expect the Huskies to pull off the upset and advance to their first Final Four since 2024, making them a strong bet on both the moneyline and spread.
