FILE - Pittsburgh Steelers linebacker Jarvis Jones, right, gets some hands-on instruction from linebackers coach Keith Butler during NFL football training camp in Latrobe, Pa., July 31, 2013. Butler retired as the team's defensive coordinator on Saturday, Jan. 22, less than a week after his 19th season with the team ended in a blowout playoff loss to Kansas City. The 65-year-old Butler, who spent 10 seasons as a linebacker for the Seattle Seahawks in the 1970s and 80s before getting into coaching, helped the Steelers win two Super Bowls and reach another during his nearly two decades with the team.
