The Ravens held a news conference at their training facility today at 2 to announce coaching changes related to the departure of defensive coordinator Rex Ryan. The new defensive coordinator will be linebackers coach Greg Mattison, who has a long history with the Harbaugh coaching family.
Mattison coached under Jack Harbaugh at Western Michigan in the early 1980s and was on the same staff when young John Harbaugh was learning the family trade. He has never been an NFL coordinator, but was co-defensive coordinator for three years at the University of Florida.
The Ravens also announced they have promoted special teams coordinator Jerry Rosberg to Assistant Head Coach and that Vic Fangio will coach the linebackers.
