Joe Whitt‘s time in the nation’s capital came to an end one month ago. The veteran staffer has now found his next coaching opportunity. 
The Steelers have added Whitt to their staff, as first reported by NFL Network’s Tom Pelissero. The move has since been confirmed by a team announcement. Whitt spent the past two seasons as the Commanders’ defensive coordinator, but after being stripped of play-calling duties midway through the 2025 campaign his dismissal came as no surprise. In Pittsburgh, he will hold the title of assistant head coach while also working with the team’s secondary.

Whitt’s showing in Washington left plenty to be desired, but he has a deep level of familiarity with new Steelers head coach Mike McCarthy. The two worked together in Green Bay from 2008-18. Whitt also joined McCarthy’s Cowboys staff and spent three seasons as Dallas’ defensive pass-game coordinator (a role he had experience with during his Packers stint as well).
An NFL coach dating back to 2007, Whitt has served in a number of capacities over the years. The 47-year-old’s first defensive coordinator gig came about when he followed Dan Quinn from Dallas to Washington. The fact things did not go according to plan with the Commanders will likely limit his future DC opportunities. Still, Whitt will look to rebuild his stock by working with a Steelers group which ranked 29th against the pass in 2025.
In other Steelers staffing news, longtime NFL defensive tackle Domata Peko has been hired. He will be Pittsburgh’s defensive line coach in 2026. Peko began his coaching career on McCarthy’s Cowboys staff in 2024. Last season, he coached Colorado’s defensive line but a reunion with McCarthy will bring about a return to the pro ranks for the coming campaign.
The Steelers have also announced the hiring of Patrick Reilly. He will serve as the team’s defensive quality control coach. Reilly worked as an offensive assistant with the Texans in 2025, but he was recently let go. Prior to his one-and-done Houston stint, Reilly worked on the defensive side of the ball during a four-year run in Jacksonville. This Pittsburgh hire will see him return to a familiar role.
