Jim Harbaugh has officially added to his defensive staff this offseason.

Saturday, Michigan officially announced the addition of Bob Shoop as the new safeties coach and Brian Jean-Mary as the linebackers coach. Assistant coach Jay Harbaugh has been promoted to special teams coordinator, as well.

It had been reported earlier this week that Shoop would be coming to Michigan after spending two years on Joe Moorhead’s staff at Mississippi State as the defensive coordinator. He also had previous stops at Tennessee, Penn State and Vanderbilt.

Jean-Mary comes to Ann Arbor after spending the previous three seasons at USF. On Charlie Strong’s staff, Jean-Mary was the assistant head coach, defensive coordinator and linebackers coach.

The addition of Jean-Mary and Shoop — and the new title for Jay Harbaugh — comes after Anthony Campanile left for the Miami Dolphins and Chris Partridge took a job at Ole Miss. Michigan also lost defensive analyst Nate Woody to Army.

Both Jean-Mary and Shoop have extensive experience on the sidelines and should fit in well in Ann Arbor.
