Dianna Russini of TheAthletic.com broke the news, shedding light on the Lions' latest addition.

Williams, who had been serving as the Tennessee Titans' defensive line coach since 2018, will bring his expertise and experience to Detroit. Last season, he was also promoted to assistant head coach, showcasing his leadership abilities.

This hiring decision holds special significance as Lions head coach Dan Campbell and Williams have crossed paths before. During the 2015 season with the Miami Dolphins, Campbell was the tight ends coach before taking over as interim head coach after four games. At that time, Williams was the defensive line coach for the Dolphins, highlighting their past collaboration.

While the Lions have not officially made any announcements regarding Williams or the 2023 defensive line coach, John Scott, this development is a strong indicator of the team's commitment to strengthening their defensive unit. The addition of Williams as the defensive line coach and defensive run game coordinator is expected to bring a fresh perspective and boost the overall performance of the Lions' defense.

With the new coaching staff in place, the Lions will be looking to make significant strides and improve their defensive line play and overall run defense. Fans and analysts will be eagerly awaiting the upcoming season to see the impact of this coaching staff shake-up on the team's performance.

The Detroit Lions, in their pursuit of success, continue to make key moves to elevate their coaching staff. The addition of Terrell Williams as the defensive line coach and defensive run game coordinator is a clear indication that the Lions are committed to building a formidable defense in the seasons to come.
