Michigan State’s Defense Has a Lot to Fix Ahead of Hosting Michigan

Defensive Struggles Highlight Michigan State’s Challenges

As the Michigan State Spartans gear up to face their bitter rival, the University of Michigan Wolverines, on Saturday night, their defensive woes have become a pressing concern. The team’s performance against Indiana in their last game showcased significant deficiencies that need addressing urgently.

Analysis of Recent Performance

During the loss to No. 2 Indiana on October 11, 2025, Michigan State’s defense was outmaneuvered and outperformed by a younger opponent. Senior wide receiver Elijah Sarratt’s experience against true freshman cornerback Aydan West did not translate into victory as Heisman candidate Fernando Mendoza completed several crucial passes. The critical moment came when rookie tight end Riley Nowakowski escaped a potential tackle, gaining 39 yards on third-and-17, setting up a touchdown.

Coach Jonathan Smith emphasized the need for better tackling techniques and physicality. “We’ve got to do a better job of going lower,” Smith noted. “When we go high on tackles, we’re often bouncing off players.” The coach also highlighted that poor leverage plays a significant role in allowing explosive gains.

Defensive Coordinator Joe Rossi’s Approach

Under new defensive coordinator Joe Rossi, Michigan State has struggled to maintain the same level of performance seen last season. Last year, the Spartans limited explosive plays and ranked ninth nationally with only six plays of at least 40 yards. However, through seven games this season, they have already allowed eight such plays, indicating a significant decline.

Smith acknowledged the difficulties: “A lot more has gone wrong for Michigan State in all three phases leading to a four-game losing streak and questions about my job security.” The coach stressed that creating turnovers remains a priority despite their current struggles. The team needs to improve its pass rush, as they have only gained two turnovers in four Big Ten games.

Preparation Against Michigan

The Spartans will face a formidable challenge from the Wolverines, who have won three straight in the rivalry and boast a potent offense led by true freshman quarterback Bryce Underwood. His strong running game is spearheaded by Alabama transfer Justice Haynes (1,139 yards) and Jordan Marshall (12 rushing touchdowns).

Michigan’s offensive prowess will test Michigan State’s defensive improvements. The Spartans must focus on preventing open-field missed tackles to avoid giving up big plays. They also need to capitalize on turnovers, as their five forced turnovers are tied for 115th nationally.

Pivotal Game for Michigan State

The outcome of this rivalry game could be a turning point for Michigan State’s season. With the defense reeling and questions surrounding head coach Jonathan Smith’s job security, every play counts in what promises to be an intense matchup. The Spartans must demonstrate significant improvement if they hope to avoid extending their losing streak.
