Greg Williams enters his third season with the Los Angeles Rams as the inside linebackers coach. He joined the Rams coaching staff after spending a season with the Green Bay Packers as their defensive pass game coordinator.
In 2025, Williams helped inside linebacker Nate Landman unlock a new level of play, as he set career-highs in tackles (132), passes defended (six), forced fumbles (four) and sacks (2.5) while also catching one interception. His partner in the middle, Omar Speights, also set a new career-high in tackles (85) under Williams' guidance.
Additionally, rookie ILB Omar Speights burst onto the NFL scene in Week 8 and finished the season leading all rookies in tackles from that point on with 66. Speights tied for the ninth-most tackles by a rookie in franchise history despite starting just 10 games. According to Pro Football Focus, Speights finished the season with the best run defense grade (77.6), best tackling grade (82.3) and the fourth-best defensive grade (69.4) among rookie linebackers. His 94.1 PFF grade in Week 13 was the highest grade among all defenders and he was named to the PFF Defensive Team of the Week.
During his time in Green Bay, Williams helped the Packers defense finish ninth in opponent pass yards per game (206.8), opponent passing yards allowed (3,515) and opponents percent of passing attempts resulting in sacks (8.6%). The Packers secondary also finished eighth in opponent completions allowed (342) and tied for 10th in opponent passing touchdowns allowed (21).
Before his season in Green Bay, Williams spent four seasons with the Arizona Cardinals as their cornerbacks coach from 2019-22. In his final season with the Cardinals, he guided a cornerback group that finished second in the league in yards allowed per completion (10.10), the best single-season mark for the team since the 1970 AFL-NFL merger. Arizona also allowed only 40 completions of 20 or more yards, which tied for third-best in the NFL.
In 2021, Williams helped the Cardinals defense finish seventh in takeaways (27) and eighth in points allowed (349). The unit also finished seventh in opponent pass yards allowed per game (214.4) and tied for 11th in opponent completions allowed (367). CB Byron Murphy finished the season tied for 12th in the NFL in interceptions (four).
Williams helped the Cardinals defense finish 10th in the NFL in opponent pass yards per game (226.4) and passing yards allowed (3,623). The unit also ranked 14th in opponent passing touchdowns allowed (26). Cornerbacks Patrick Peterson and Dre Kirkpatrick combined for six interceptions (three each) on the season. Murphy also registered 2.0 sacks and two fumble recoveries and was one of only two cornerbacks to register multiple sacks and fumble recoveries that season. He became the first Cardinals cornerback to accomplish that feat in a season. In 2019 under Williams' guidance, Murphy started all 16 games as a rookie and finished third among rookies in passes defensed (10).
Prior to his stint in Arizona, Williams spent the 2018 campaign with the Denver Broncos coaching the defensive backs. With Williams help, the Broncos defense tied for fifth in the NFL with 17 interceptions and CB Chris Harris Jr. was selected to the Pro Bowl after posting a team-best three interceptions along with a sack. Additionally, Safety Justin Simmons finished second on the team with 97 tackles (71 solo). The Broncos held opponents to 27 points or less in 14 games that season, which tied for the most in the NFL.
From 2016-17, Williams coached defensive backs for the Indianapolis Colts, where he mentored S Malik Hooker who finished third among NFL rookies with three interceptions despite playing in just seven games in 2017. That season, DB Rashaan Melvin recorded 10 pass breakups, which was tied for 22nd-most in the NFL. The Colts defense also finished fifth in opponent completions allowed (324) that season.
In 2016, Williams helped DB Vontae Davis finish tied for 17th in the league in pass breakups (11). DB Darius Butler also ranked tied for eighth in interceptions (three) that season.
Williams also served as the assistant secondary coach for the Chargers from 2013-15 where he worked with S Eric Weddle, who was selected to the Pro Bowl in 2013 and 2014. The Chargers defensive unit finished the 2014 season ranked fourth in the league in opponent passing yards per game (214.2) and ninth in total defense.
Before working with the Chargers' secondary, Williams spent four seasons as their assistant linebackers coach from 2009-12. In 2012, he was part of a staff that helped the Chargers finish ninth in total defense allowing 326.4 yards per game and sixth in rushing defense allowing 96.4 rush yards per game. The defense registered 38.0 sacks on the year, which tied for 11th in the NFL, and 21.0 of the sacks came from linebackers which included Shaun Phillips who had a team-high 9.5 on the year.
In 2011, Williams mentored LB Antwan Barnes, who posted a career-high 11.0 sacks despite starting just five games that season. The year prior in 2010, the Chargers were first in the NFL in total defense allowing 271.6 yards per game and passing defense allowing 177.7 passing yards per game. They were also tied for second in sacks (47.0) and Phillips notched a team-high 11.0 sacks on the way to earning his first Pro Bowl selection. In 2009, Phillips led the NFL with a career-best seven forced fumbles and LB Stephen Cooper added a career-high three forced fumbles.
