At least he should be used to wearing khaki pants before arriving at Ann Arbor.

Michigan made it official on Sunday afternoon, announcing the addition of Mike Macdonald as their defensive coordinator. Macdonald had last served as linebackers coach for the Baltimore Ravens.

Interestingly enough, Macdonald’s new boss at Michigan, Jim Harbaugh, is the brother of his former head coach with the Ravens, John Harbaugh.

It is a big time hire for the Wolverines. He replaces popular defensive coordinator Don Brown, who had been in Ann Arbor since 2016.

The Ravens crashed out of the playoffs on Saturday night with a 17-3 loss to the Buffalo Bills.

Macdonald has a strong recent resume in the NFL, having been with the Ravens since 2014 where he started as a defensive assistant and worked his way up to defensive backs coach and now, for the past three seasons, as their linebackers coach.

Last season, Michigan gave up 34.5 points per game, third-worst in the NFL. Michigan finished the season a disappointing 2-4.

Macdonald’s prior college experience comes for three seasons, beginning in 2011, where he was a linebackers coach at Georgia.
