Karl Dunbar

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.

Among NFL defensive tackles in '19, Heyward ranked second in quarterback hits, second in sacks and fourth in tackles for loss.

Another Dunbar protege, nose tackle Javon Hargrave, recorded 60 tackles, 7 tackles for loss, 6 quarterback hits, 4.0 sacks and 1 forced fumble in 2019. Hargrave's 60 tackles were the most among all nose tackles in the NFL and ninth-most among defensive tackles. Among all NFL nose tackles in '19, Hargrave ranked tied for second in sacks, quarterback hits and tackles for loss.

Three members of Dunbar's positional group recorded at least 5.0 sacks each, led by defensive captain and first-year Pro Bowl selection Heyward. Heyward's 8.0 quarterback takedowns in 2018 led the defensive line, fol- lowed by Javon Hargrave (6.5), Stephon Tuitt (5.5) and Daniel McCullers (1.0). Pittsburgh's defense finished sixth among all NFL teams in rushing yards allowed and total yards allowed per game in 2018 (96.1 / 327.2), with just two running backs eclipsing 100 rushing yards against the Steelers on the season.

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 in total defense (260.4 yards per game allowed) and rush 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 54.0 sacks.

In 2015, Dunbar served as the defensive line coach of the Buffalo Bills, where he reunited with defensive tackle Kyle Williams whom he coached at Louisiana State University.

Dunbar oversaw a defensive line with the New York Jets for three seasons (2012-14) that featured the 2013 Associated Press Defensive Rookie of the Year — Sheldon Richardson — who also earned Pro Bowl honors in 2014. Richardson totaled 11.5 sacks during his two seasons under Dun- bar's tutelage — the fifth-most among all AFC defensive tackles during that period. Muhammad Wilkerson, a Jets defensive lineman, also benefited greatly under Dunbar's guidance, posting a team-leading and career-high 10.5 sacks in 2013 — the most by a Jets defensive player since 2005. Wilkerson was named second-team All-Pro by the Associated Press and a first alternate for the Pro Bowl.

Before joining the Jets, Dunbar served as the defensive line coach of the Minnesota Vikings from 2006-11. Minnesota's defense allowed the fewest rushing yards in the NFL (84.8 yards per game) and recorded the sixth-most sacks in the League (242.0) during Dunbar's six-years with the Vikings. The Vikings' rush defense was the best in the NFL in three consecutive years from 2006-08, marking the first time since the 1970 AFL-NFL merger that a team had the number one rushing defense in three consecutive seasons.

Three Minnesota defensive linemen were selected to multiple Pro Bowls while Dunbar was the unit's position coach: defensive tackle Kevin Williams (5), defensive end Jared Allen (4) and defensive tackle Pat Williams (3). The trio earned the honor of being the first Viking triplet of defensive lineman to earn the Pro Bowl in the same season since 1969 in 2008 — a season in which they led the League in rush- ing defense for the third straight year.

In 2011, the Vikings' defense finish tied for the most sacks in the NFL with 50.0, an effort led by Allen's NFL-leading 22.0 sacks — just a half-sack shy of the League's single-season record.

The Vikings defense allowed just 985 rushing yards in Dunbar's second season with the franchise — setting a franchise record and ranking second in the NFL since the 1970 AFL-NFL merger behind the Ravens' 970 yards allowed in 2000.

In 2005, Dunbar coached the defensive line at Louisiana State University, which featured Buffalo Bills defensive tackle Kyle Williams.

Dunbar's first coaching stint in the NFL was with the Chicago Bears in 2004. He guided a young defensive line that included rookie first-round pick Tommie Harris and second-round selection Tank Johnson. Dunbar was the defensive line coach at Oklahoma State University from 2002-03, where he mentored future Viking Kevin Williams and helped him become the program's first defensive lineman to be a first- round selection (ninth in 2003) since Leslie O'Neal (eighth in 1986).

He began his coaching career at Opelousas (Opelousas, La.) High School in 1986 before advancing to Beau Chene (Arnaudville, La.) High School in 1997.

Dunbar, an eighth-round draft selection of the Steelers in 1990, played defensive line for two teams in his NFL career: New Orleans Saints (1992-93) and Arizona Cardinals (1994-95). He also played one season in NFL Europe (Rhein Fire, 1995).

Dunbar was a member of a Louisiana State University defense as a player while current Steelers Assistant Head Coach John Mitchell was on the Tigers' coaching staff.

Dunbar and his wife, Pamela, have three children: Karmichael Mackenzie II, Mickel Angelle and Nickolette Alyse. A native of Opelousas, La., Dunbar graduated from Louisiana State University with a bachelor's

degree in criminal justice.
