The Steelers hired Karl Dunbar to coach the defensive line ahead of the 2018 season and it paid dividends throughout the year. He seemed to get these guys to the next level.
The Steelers defensive line accounted for 21 of the team’s 52 sacks on the season. They also recorded 48 of their 115 QB hits. The defensive line flourished in Dunbar’s first year.
McCullers was the best he had been his entire career and showed more of the player they wanted him to be since drafting him. Dunbar has done wonders for the unit.
Outside the starting three and McCullers, the Steelers are left with L.T. Walton and Tyson Alualu. The two have been quality depth but the Steelers could look to upgrade their depth at the position in 2019.
There are some free agents who could peak the Steelers interest to fill depth. The starters are set for 2019 and they can improve even more next season.
