The Cowboys were set to enter the 2024 NFL season with defensive end as a position of strength. Unfortunately, an early training camp injury has changed that picture a bit in Dallas. According to Tom Pelissero of NFL Network, defensive end Sam Williams is reported to have suffered a torn ACL, ending his third year in the league before it had a chance to get off the ground. After initial speculation from Pelissero and the team, Ian Rapoport was the one to confirm the positive MRI results. 
Williams joined the Cowboys’ defensive front in 2022 after getting drafted out of Ole Miss in the second round. His rookie year saw him buried on the depth chart behind Micah Parsons, DeMarcus Lawrence, Dorance Armstrong, and Dante Fowler, yet he still managed to tally four sacks while rotating in. He also showed his disruptive nature in other ways, finishing only behind Parsons on the team with 10 tackles for loss.
In his sophomore campaign, Williams worked his way past Fowler on the depth chart and even outproduced Lawrence, finishing the season third on the team in sacks with 4.5. Pro Football Focus (subscription required) has been friendly to Williams over the years, ranking him as the 54th-best pass rusher out of 119 at the position in 2022 and the 51st out of 112 in 2023 — both years in limited time. Last year, PFF graded him with the 37th-best pass rushing grade in the league.
Up to now, health had hardly been an issue for Williams. In two years of NFL play, Williams only missed two games, both in his rookie season, and one of them was the result of a car accident. He was arrested shortly before the 2023 season but didn’t end up missing any time as a result of the incident.
With two of his competitors for snaps, Armstrong and Fowler, now set to take starting reps for the division-rival Commanders, Williams was in line for a larger responsibility and snap share in 2024. After running fifth and fourth on the depth chart in his first two seasons, Williams had once again worked his way up and was set to run as the third defensive end for the year.
The team utilized a second-round pick on Western Michigan’s Marshawn Kneeland in April to helps minimize the impact of Armstrong and Fowler’s departures, but now, Kneeland will likely be asked to step up into the role Williams was set up for. Kneeland wasn’t an elite pass rusher for the Broncos, only amassing 13.0 sacks in five years; his seasons in college actually much resembled the NFL production of Williams’ first two years, so perhaps he’s well-equipped to step into that role.
Unless Dallas turns to the veteran free agent market, which they may have to do, the Cowboys will have to rely on other players for that lost depth. Viliami Fehoko returns in 2024. A fourth-round rookie last year, Fehoko failed to make any game appearances before being placed on injured reserve with a knee injury in mid-November. He was activated in January but still didn’t see the field. Tyrus Wheat is the other depth option after appearing in 12 games for the Cowboys last year as an undrafted rookie.
While that may not be enough for Dallas, and they may need to seek some free agent help, one thing that’s certain is that Williams will not be able to contribute this year. That makes 2025 a crucial year for Williams as it will be the final year of his rookie contract and his final chance to show what he can bring to a defense that already rosters an All-Pro star in Parsons.
