Michigan and Tennessee are meeting in a rematch of a second-round game from 2022, when Michigan picked up a 76-68 win. Both rosters look entirely different now, with Michigan considered one of the true contenders to win the title. Tennessee is the lowest-ranked team remaining in the field, and it is a 7.5-point underdog in the Sunday college basketball odds at Caesars.  

The other game on Sunday features Connecticut, with that game beginning at 5:05 p.m. ET. Connecticut won back-to-back championships in 2023 and 2024, and it is aiming for a third title in four years. It is a 5.5-point underdog tonight, while the over/under is 133.5. Bet on college basketball and more at Caesars with the promo code SPORTSLINEDYW to double your winnings on 10 bets:
