It also marked the school's ninth conference championship under Tom Izzo. They finished the season 32–7, 16–4 to earn a share of the Big Ten championship. As the No. 1 seed in the Big Ten tournament, they defeated Ohio State, Wisconsin, and Michigan for the third time on the season to win the tournament championship. The win over Ohio State on March 15, marked Tom Izzo's 600th career win. The Tournament win marked the school's sixth championship, the most in the Big Ten. The Spartans received the conference's automatic bid to the NCAA tournament as the No. 2 seed in the East Region. There they defeated Bradley and Minnesota to advance to the team's first Sweet Sixteen since 2015. In the Sweet Sixteen, they defeated No. 3-seeded LSU to advance to the Elite Eight.
