Louisville Cardinals vs Michigan State Spartans Odds & Analysis

Odds as of March 21, 2026, 11:08 a.m. ET from BetMGM.

When analyzing the statistics for this matchup, the Michigan State Spartans feature an incredibly efficient and balanced attack. Carson Cooper has been a dominant force in the paint, recently putting up 31 points and 10 rebounds while shooting an excellent 7-for-9 from the floor. He is supported by Coen Carr (20 points) and Jaxon Kohler (16 points, 9 rebounds). The offense runs seamlessly through Jeremy Fears Jr., who has been a standout facilitator with 11 assists to his name. Defensively, the Spartans have stifled their opponents, and they will need that defensive tenacity against a dangerous Cardinals backcourt.

For the Louisville Cardinals, success will heavily depend on their perimeter shooting. Isaac McKneely has been virtually unstoppable from beyond the arc, hitting 7 of his 10 three-point attempts on his way to a 24-point performance in his last outing. Down low, Sananda Fru provides critical rebounding and interior scoring, tallying 18 points and 10 rebounds on 80% shooting. While Ryan Conwell has struggled slightly from the field, he still manages to impact the game with his playmaking, dishing out six assists.

Best Bets & Predictions:

• Against the Spread: Michigan State Spartans -4.5 (-115). The Spartans’ ability to lock down defensively (allowing just 67.0 points per game compared to Louisville’s 79.0 points allowed per game) gives them a distinct edge. With Cooper and Kohler controlling the glass, Michigan State should be able to cover the modest spread.
• Total Points: Over 151.5 (-115). Both teams have showcased explosive offenses in the postseason. With the Spartans averaging 92.0 points per game and the Cardinals scoring 83.0 points per game, this game has all the makings of a shootout, especially if McKneely stays hot from three-point range.
