There’s been a pipeline of sorts between Baltimore and Ann Arbor between the Baltimore Ravens and Michigan Wolverines. Ravens head coach John Harbaugh and Michigan head coach Jim Harbaugh are brothers with a good relationship that share a lot of the same football philosophies. This dynamic has created coaches heading from the Ravens to the Wolverines, and vice-versa.
For example, Michigan hired Mike Macdonald as defensive coordinator in 2021, he was previously Baltimore’s linebackers coach. In the same cycle Michigan hired Matt Weiss from Baltimore — Weiss coached everything from defense to quarterbacks to running backs for the Ravens.
