After five relatively successful seasons in Ann Arbor, Don Brown was painted as the sacrificial lamb and dismissed over the winter, following a season unlike any other. Despite finishing among the top 10 nationally in total defense every year prior, Brown was let go after the Wolverines dropped to 56th in the category last season.
But while Jim Harbaugh's defense was struggling to keep its head above water, his brother's was sitting near the top of the NFL's ranking yet again. In 2020, John Harbaugh's Ravens finished second in points allowed and seventh in both total yards-allowed and yards-per-play allowed.
