If it isn’t broke, don’t fix it.

According to Fox Sports’ Bruce Feldman, Don Brown, the first-year defensive coordinator at Michigan, earned himself a five-year contract with the Wolverines thanks to how his defense performed in 2016.

Before coming to Michigan, Don Brown was the defensive coordinator at Boston College where he had the Eagles’ defense lead the country in eight categories while finishing second in two others. This season, with the Wolverines, Brown finished with the No. 2 defense in the country.

Michigan led the country this past season in third-down defense and finished only behind Alabama in yards per play allowed at 4.21. Prior to his time at Boston College, Brown was a defensive coordinator at Maryland (2009-2010) and Connecticut (2011-12) after being the head coach at UMass.
