ORLANDO, Fla. -- Veteran assistant coach John Marshall, who assumed the role of Seattle Seahawks defensive coordinator in 2005 after Ray Rhodes suffered two mild strokes, has been officially elevated full-time to the position by coach Mike Holmgren.
Rhodes, hired as coordinator in 2003, will serve as a consultant for the 2006 season.
"Since it's how we pretty much functioned [last season]," Holmgren said, "it's not that big a deal. It isn't as if John hasn't done it before, and he did a great job under tough circumstances last year."
Marshall, 60, has twice previously been a coordinator in the league and is a highly regarded assistant. He took over last year when Rhodes' workload was dramatically reduced and Holmgren limited his time in the office, and Seattle players and coaches said the transition was a seamless one.
Out of respect for his colleague, Marshall refused to move into Rhodes' office last season, but will do so now. It is not yet known how much Rhodes, 55, will work during the week.
In addition to the Marshall promotion, Holmgren confirmed the hiring of former Arizona and St. Louis defensive coordinator Larry Marmie as assistant secondary coach. Former defensive quality control aide Zerick Rollins will move into Marshall's old spot as the linebackers coach.
