Most Coaching Staff Transition In John Harbaugh Era

John Harbaugh is in unfamiliar territory this offseason.

His coaching staff is going through significant transition, and he has replaced more assistants than ever during his time in Baltimore.

The Ravens have lost or parted ways with six assistant coaches, including the bulk of the offensive staff.  Harbaugh has never lost more than four assistant coaches in an offseason. Every offensive position coach from last season is gone, and Gary Kubiak is now the offensive coordinator after the Lions hired Jim Caldwell as their head coach.

"It is a fresh start," Harbaugh said last week when Kubiak was hired. "It's new and it's exciting, and we really can't wait to get going."

Here's a look at the coaches the Ravens have lost in each of the last six offseasons:

The transition is a combination of an offensive shift with the arrival of Kubiak and the Ravens' success with creating opportunities for assistant coaches. Caldwell was the third coordinator to get a head coaching job during Harbaugh's tenure, and he brought former Secondary Coach Teryl Austin with him to Detroit as his defensive coordinator.

Former defensive coordinators Rex Ryan (Jets) and Chuck Pagano (Colts) were both plucked from Harbaugh's staff for head coaching jobs.   

"A lot of great things have been done here. The coaches who have been here, we're all proud of those guys," Harbaugh said last week. "Guys have gone on to other things; some guys are here. That's the way it works in the National Football League, and we all know that."

Kubiak's arrival also led to changes on the offensive staff, as this was the first time Harbaugh has gone outside the organization to hire a new coordinator. The previous coordinator hires – Mattison, Pagano, Dean Pees and Caldwell – were all internal promotions.

Bringing in a coordinator from another team to implement a new system naturally leads to changes among the staff. Kubiak brought Quarterbacks Coach Rick Dennison and Tight Ends Coach Brian Pariani with him from the Houston Texans, and then Hostler and Moeller both decided to move onto other opportunities. Hostler took a senior offensive assistant position with the Buffalo Bills and Moeller became the offensive line coach for the Browns after it was decided that Juan Castillo would be the Ravens' offensive line coach next season. (Castillo moved from run game coordinator to offensive line coach.)

The Ravens also parted ways with both Harman and Montgomery, but they have not yet joined another team.

Defensively, former senior assistant Steve Spagnuolo has taken over as the secondary coach. The rest of the defensive staff has remained intact from last season.

Harbaugh and Kubiak still have to finish finalizing the offensive staff by adding a running backs and receivers coach, and the Ravens have already started the process of interviewing coaches to fill those jobs.

 "We're going to build a great coaching staff again this year," Harbaugh said.
