Karl Dunbar is entering his second season as the Steelers' defensive line coach and his 13th year as a defensive line coach in the National Football League in 2018. He was hired by the Steelers on February 8, 2018.
Dunbar re-entered the NFL coaching ranks after spending the two years as the defensive line coach at the University of Alabama. At Alabama, Dunbar tutored a defensive line that helped the school capture the College Football Playoff National Championship following a 2017 campaign, and advanced to the game after the 2016 season. The Crimson Tide defense led the nation on total defense (260.4 yards per game allowed) and rushing defense (94.7 yards per game allowed) in 2017. In his first season at Alabama, the Crimson Tide defense led the nation in rushing defense, yielding just 63.9 yards per game and ranked fourth in sacks (3.6 sacks per game) while recording a school-record 54 sacks.
