🚨 BREAKING: Cowboys’ Defensive Line Coach Aaron Whitecotton Joins Titans, Reunites with Robert Saleh 👇
In a move that has taken the NFL coaching world by surprise, Aaron Whitecotton, the defensive line coach for the Dallas Cowboys, is heading to the Tennessee Titans to take on the same role. This marks a reunion with Robert Saleh, who now leads the Titans after a successful stint as the Jets’ head coach. Whitecotton and Saleh have worked together at multiple stops in their careers, and their strong professional relationship makes this transition almost inevitable.
A Career Built on Strong Relationships
Whitecotton’s move to Tennessee is a testament to the importance of relationships in the NFL coaching ranks. Just weeks ago, Whitecotton interviewed for the Cowboys’ defensive coordinator job after an impressive year rebuilding the team’s defensive line. Despite his efforts, Dallas ultimately hired Christian Parker, the Eagles’ secondary coach, for the job. This decision seemingly indicated that the Cowboys didn’t see Whitecotton as a fit for a larger role, leaving the door open for his departure. Days after the Cowboys made their choice, Whitecotton was on his way to Tennessee.
The connection with Robert Saleh made this move almost inevitable. The two have a longstanding relationship, having worked together at three different locations: Jacksonville (2014-2016), San Francisco (2020), and New York (2021-2024). Their familiarity with each other’s systems and expectations played a significant role in Saleh’s decision to bring Whitecotton to the Titans as defensive line coach. With Saleh calling the defense in Tennessee, Whitecotton became a natural fit to work with the Titans’ standout defensive lineman, Jeffrey Simmons, and manage the trenches.
Dallas’ Defensive Line Transformation: A Big Loss
For the Cowboys, Whitecotton’s departure is a major blow to a defensive unit that he helped transform over the course of the 2025 season. When Whitecotton arrived in Dallas last offseason, his task was clear: fix the defensive line, which had been one of the team’s biggest liabilities in 2024. By season’s end, Whitecotton’s work had paid off. The Cowboys’ front four went from a major weakness to a functional and much-improved unit.
A key turning point for the Cowboys came during the trade deadline when they acquired Quinnen Williams from the Jets. The pairing of Williams and Whitecotton proved to be a successful one, and Williams himself credited Whitecotton for his growth as a player. Williams, who had previously been a solid but unspectacular defensive tackle, blossomed under Whitecotton’s tutelage. He went on to become a Pro Bowler and All-Pro, with Williams attributing much of his success to Whitecotton’s coaching. “Before Whitecotton, I kind of was set out to be a good DT,” Williams said. “But after this coach came into my life, I became an All-Pro and a Pro Bowler.”
That partnership, which was beginning to click, now leaves the Cowboys with a big void to fill on their coaching staff. Whitecotton’s impact in Dallas was significant, and his departure represents a missed opportunity for the Cowboys to continue developing their defensive line and building on their success.
What’s Next for the Cowboys and the Titans?

For the Titans, Whitecotton’s arrival could be a game-changer. Under his guidance, the Titans’ defensive line could become one of the most feared units in the NFL. Working with a talented player like Jeffrey Simmons will give Whitecotton the opportunity to showcase his coaching ability once again, and Titans fans are hoping to see the same level of growth and success that Whitecotton brought to the Cowboys and Jets.
As for the Cowboys, the search for a new defensive line coach begins, and the team will need to quickly move forward to ensure that the progress made in 2025 is not lost. Whitecotton’s exit leaves a hole in a key area of their defense, and it will be crucial for Dallas to find a coach who can continue the work he started and help the defensive line remain a strength for the team moving forward.
Saleh’s Press Conference Delayed
Meanwhile, the Titans’ press conference to introduce Robert Saleh as their new head coach has been delayed due to the aftermath of a significant winter storm in the Nashville area. Power outages and other weather-related issues have impacted the region, but fans can expect to hear from Saleh on Thursday at 2 p.m. CT.
As the coaching staff in Tennessee begins to take shape, the addition of Whitecotton and the strong connection between Saleh and Whitecotton could help set the foundation for a successful defensive unit in 2026.
