The Pittsburgh Steelers have enjoyed incredible defensive line play for most of the last decade, headlined by T.J. Watt and Cameron Heyward. Coaching that group for the majority of that time was Karl Dunbar, who once upon a time was drafted by Pittsburgh in the eighth round. Dunbar wasn't retained when Mike Tomlin stepped down as head coach, landing with the Jets on Aaron Glenn's staff.
Replacing him is former NFL defensive lineman Domata Peko, a name Steelers fans know well from his decade playing with the Cincinnati Bengals. Peko has quickly climbed the coaching ranks, going from the Dallas Cowboys as a defensive assistant in 2024 to his position with the Steelers just two years later. While he lacks the coaching experience that Dunbar brought to the table, he has reportedly brought an entirely new energy that is being well-received by his players.
While speaking on the Steelers Collective podcast, the Pittsburgh Post-Gazette's Ray Fittipaldo explained that Peko's style is a big contrast to the more laid-back Dunbar.
"I'm gonna go with an energy guy, and I don't think there could be more of a contrast between this new position coach and the position coach he replaced, and that's Domata Peko," Fittipaldo said. "Karl Dunbar was a pro, man, but he was very laid back. If there was ever a reason to make a change, and I know it only happened because of [Mike]Tomlin, but that defensive line group needs some spark and needs some energy."

Fittipaldo would go on to add that he believes that the change in energy could be exactly what the group needs, especially the veteran stars.
"Just listening to Peko talk that one day we got to talk to him down at the indoor complex, man, he just has a ton of energy, man. I love it. I think it's gonna be real good for Cam. Obviously, great for those young guys like Keeanu Benton, Derrick Harmon. I think they need someone like that coaching that position."
In the NFL, sometimes making coaching changes is less about the quality of the coach and more about the kind of coach a team needs. Dunbar did a fantastic job overall coaching his unit, but with Mike McCarthy coming in as the new HC, he clearly felt like Peko was better suited for what that group needs to take a step forward.
Despite seemingly getting better with age, Heyward is entering his age-37 season. Keeanu Benton is entering a pivotal contract year (assuming he doesn't ink a new deal before the season), and Derrick Harmon is looking to cement himself as a part of the Steelers' future. Having a younger, more energetic coach like Peko is likely a better fit to get the most out of them in 2026 and beyond.
We won't truly know if the Peko hire was the right one until we see the results on Sundays, but it sure sounds like he is starting his tenure with the Steelers on the right foot.
