Keith Butler is returning as the Pittsburgh Steelers’ defensive coordinator for 2021. But it could be his final season after signing just a one-year contract that puts him again in lame duck status going forward. If and when the Steelers do make a change, defensive line coach Karl Dunbar may finally get his shot.
Some fans may forget who Dunbar even is. But he’s done a tremendous job filling the big shoes left by John Mitchell. Dunbar was hired by the Steelers in 2018 to replace Mitchell, who moved to an assistant/liaison type of role after being the team’s d-line coach for over two decades.
