Mike Tressel (Wisconsin Defensive Coordinator)
Mike Tressel, currently Wisconsin's defensive coordinator, is another intriguing candidate with a strong Big Ten background. Having coached under Mark Dantonio at Michigan State and Luke Fickell at Cincinnati, Tressel has experience leading tough, disciplined defenses built to stop physical offenses.
One of the biggest benefits of hiring Tressel is that he's a proven recruiter in the Midwest. Michigan football has traditionally relied on building strong defensive rosters with homegrown talent, and Tressel's ties to Ohio and Michigan high school programs could help keep that pipeline strong.
While Tressel might not bring as much flash as Guidry, his track record of producing elite linebackers and defensive backs makes him a safe, reliable choice. If Michigan football wants a long-term solution that can sustain defensive success without constant turnover, Tressel is your guy.
