Mike Macdonald is set to become a NFL head coach this offseason, according to a report.

Macdonald is expected to be hired by the Seattle Seahawks to replace longtime head coach Pete Carroll, per ESPN’s Adam Schefter. Macdonald, 36, would be the youngest head coach in the league if the deal gets finalized.

Macdonald spent 1 year at Michigan as the program’s defensive coordinator in 2021. After that lone season with the Wolverines, he went back to the Baltimore Ravens to work for John Harbaugh as their defensive coordinator. He was previously the Ravens’ linebackers coach from 2018-2020.

Macdonald’s lone season in Ann Arbor produced the first of 3 consecutive Big Ten Championships and College Football Playoff appearances. Macdonald brought Michigan to 5th in the Big Ten (up from 10th the previous year) in yards per play defense in 2021.

Michigan replaced Macdonald with Jesse Minter ahead of the 2022 season. That proved to be a great decision by the Wolverines, as Minter’s defense helped lead the program to its first national championship since 1997 this past season. Minter is expected to head to the Los Angeles Chargers as well alongside Jim Harbaugh.
