Biff Poggi, 65, who previously worked at U-M as an analyst in 2016 and then as associate head coach in 2021-22, has returned for the same role.

Biff Poggi is set for his third stint in Ann Arbor, after helping spark the program's turnaround in the middle of Harbaugh's tenure.

Campbell joins an organization that includes nine other Michigan coaches who served under Harbaugh’s National Championship staff. The most prominent name among them is defensive coordinator Jesse Minter, who also ran the Wolverines’ defensive unit in 2023.
