Straight out of football coach central casting.

It's officially official: Michigan formally announced the hiring of Boston College's Don Brown as defensive coordinator. From the press release:

University of Michigan J. Ira and Nicki Harris Family Head Football Coach Jim Harbaugh announced Monday (Dec. 21) the hiring of Don Brown as defensive coordinator. Brown will start his appointment with the program after the conclusion of the bowl season.

"We are very pleased and happy to announce that our top candidate and number one choice, Don Brown has accepted our offer to become defensive coordinator," said Harbaugh. "After a very thorough search and talking with those I respect the most in this game, including Jack Harbaugh, John Harbaugh, Bill Belichick, Bob Sutton, Vic Fangio and others, it led me to Don Brown. Everything he has touched has turned to gold. Just look at his track record as a head coach, defensive coordinator and even as a baseball coach. We are beyond excited to welcome this high character, high achieving individual to our program and university. Teaching and player development are synonymous with coaching and Don Brown epitomizes those qualities."

Brown spent the past three seasons coordinating the defense at Boston College (2013-15). His 2015 defense currently leads the nation in eight defensive categories -- total defense, rushing defense, scoring defense, red zone defense, first down defense, third down defense, fourth down defense and tackles-for-loss -- and lists second in pass defense and pass efficiency defense.

Brown was named the 2015 AFCA Assistant Coach of the Year. He was nominated for the Broyles Award which honors the nation's top assistant in college football the past three seasons.

At BC, Brown directed one of the best defenses in the country, on par with Alabama's and Michigan's despite a massive talent gap between those programs. His hiring has received universal praise; we'll have more on that later this afternoon.
