Michigan is hiring longtime Air Force assistant Brian Knorr, who is expected to work with special teams alongside coordinator Kerry Coombs, according to CBS Sports' Matt Zenitz. Knorr arrives in Ann Arbor after working as Air Force's defensive coordinator for four seasons from 2022 through 2025. A former Air Force quarterback from 1982 to 1985, Knorr lettered three seasons and won 30 games as a collegiate player. He graduated from the Air Force Academy in 1986 with a degree in management and began his coaching career there in 1992. At Michigan, he joins a staff led by Whittingham, with Jay Hill already in place as the Wolverines' new defensive coordinator, adding another experienced voice to a staff built around proven collegiate track records.
