The Facts: The Seahawks announced three additions to their coaching staff Tuesday, naming Brian Schottenheimer offensive coordinator, Ken Norton Jr. defensive coordinator and Mike Solari offensive line coach.

Diehards Line:Kris Richard, who served as defensive coordinator the past three seasons, was relieved of his duties, as was linebackers coach/assistant head coach/defense Michael Barrow. The Seahawks relieved previous offensive coordinator Darrell Bevell and offensive line coach/assistant head coach Tom Cable of their duties last week. Norton returns to Seattle after spending the past three seasons as the Raiders’ defensive coordinator. Schottenheimer, 44, most recently served as the quarterbacks coach in Indianapolis over the past two seasons, but also has significant experience as an offensive coordinator, holding that position with the New York Jets from 2006-2011, the St. Louis Rams from 2012-2014, and the University of Georgia in 2015. Solari, 63, has enjoyed a long career as an NFL offensive line coach, including two seasons in Seattle in 2008 and 2009. He also served as Kansas City’s offensive coordinator from 2006-2007. Most recently, Solari spent the past two seasons as the offensive line coach for the New York Giants.
