The 2020 team started the season ranked No. 1 in the AP poll for the first time in school history. Senior point guard Cassius Winston was a popular pick as the preseason player of the year. However, shortly before the season, it was announced that Josh Langford had reinjured the foot that had caused him to miss most of the prior season. Langford would not play a game for the Spartans during the season. Due in part to Langford's injury, the Spartans struggled in the non-conference schedule, losing the first game of the season to No. 2 Kentucky before losing twice more in their first eight games and falling to 5–3. MSU also struggled as Cassius Winston dealt with the suicide of his brother, Zachary, on November 10, 2020. Winston did not miss a game due to the tragedy, but did struggle for a portion of the season. MSU rebounded as Winston struggled to return to his All-American form and the Spartans did not lose again until Big Ten play after starting the conference schedule 5–0. The Spartans then lost six of their next 10 games to all but assure they would be unable to win their third straight Big Ten regular season championship. The Spartans rebounded to win their final five games and come from a three-game deficit to earn a share of their third straight Big Ten championship. As the Spartans prepared for the postseason, they were once again a popular pick to win the NCAA Tournament. However, the season ended abruptly when all postseason tournaments, including the NCAA Tournament, were canceled due to the coronavirus pandemic. Cassius Winston finished his MSU career with the most assists in Big Ten history and was a consensus second team All-American for the second consecutive year.
