Karl Dunbar is entering his third season as the Steelers' defensive line coach and his 14th year as a defensive line coach in the National Football League. He was hired by the Steelers on February 8, 2018.
In 2019, Dunbar mentored defensive tackle Cameron Heyward, who was named All-Pro for the second time in his career (2017). Heyward finished the season with 9.0 sacks, 22 quarterback hits, 11 tackles for a loss and 6 passes defensed. Heyward not only led all NFL defensive tackles in stops with 83, but he also led the League in tackles by a defensive lineman. In fact, his 83 tackles were the most by a Steelers defensive lineman since Donald Evans had 84 in 1993.
