Terrell Williams

Assistant Head Coach - Defense/Defensive Line Coach


Terrell Williams is in his sixth season with the Titans and his first year as assistant head coach-defense/defensive line. It is his 26th season in coaching and his 12th campaign in the NFL. He arrived in Tennessee in 2018 as defensive line coach.  

In 2022, he helped the Titans finish first in the NFL in rushing defense, as the unit allowed only 76.9 opponent rushing yards per game, which was the second-lowest number in franchise history. Defensive tackle Jeffery Simmons was named to his second Pro Bowl after posting 7.5 sacks, while nose tackle Teair Tart recorded a career-high 16 starts. Defensive end DeMarcus Walker established career highs in several categories, including 32 tackles and seven sacks.  

In 2021, Simmons continued to emerge as one of the NFL's top young defensive talents and was named to his first career Pro Bowl after setting career highs in several categories, including sacks (8.5), tackles (54), quarterback pressures (58), tackles for loss (12) and passes defensed (six). Simmons, who also earned second-team Associated Press All-Pro honors, established a franchise single-game postseason record with three sacks in the divisional playoff contest against Cincinnati. 

In 2020, Simmons ranked second on the team with 19 quarterback pressures and became the first player in the franchise's "Titans era" (since 1999) to post at least three fumble recoveries, three sacks and five passes defensed in the same season. 

In 2019, Williams helped acclimate Simmons to the NFL as a first-round pick, while veteran Jurrell Casey earned his fifth consecutive Pro Bowl berth after posting five sacks and a team-high 30 quarterback pressures. The Titans rebounded from a 2-4 start to make the franchise's first AFC Championship Game in 17 years.  

In Williams' first season with the Titans, Casey was named to the Pro Bowl after leading the defense with seven sacks. The Titans defense ranked eighth overall (333.4 yards per game), third in points allowed (18.9 per game), 10th on third down (36.6 percent) and second in the red zone (44.7 touchdown percentage). 

Prior to his arrival in Tennessee, Williams' most recent stop was three years (2015-17) with the Miami Dolphins coaching the defensive line. During Williams' three seasons with the Dolphins, defensive end Cameron Wake tallied 29 sacks, which was the eighth-highest total by a player in that period, while Ndamukong Suh totaled the eighth-highest number of sacks (15.5) among defensive tackles. Wake's nine forced fumbles tied for fifth in the NFL over the same span.
