The Dallas Cowboys are heading into the 2026 offseason with a pressing need to redefine their defensive identity, particularly at the linebacker position. Last season, the linebackers struggled to find consistency, contributing to a defense that allowed a whopping 6.1 yards per play, the highest in the NFC. The Cowboys were near the bottom in terms of rushing success rate allowed, often letting opposing running backs break through untouched to the third level.
Across the board, both seasoned veterans and rookies faced challenges. Kenneth Murray Jr. frequently appeared out of place, Marist Liufau was regularly neutralized, and rookie Shemar James had difficulty with run fits, often misjudging gaps and opening up lanes for big plays. These issues have prompted the Cowboys to seek reinforcements in free agency.
One name buzzing around the Cowboys' camp is Quincy Williams, the older brother of standout defensive tackle Quinnen, acquired midseason last year. While there was speculation about bringing Quincy over during that trade, it didn't happen. Now, as an unrestricted free agent, the possibility of a family reunion has some fans excited.
Quincy Williams boasts an impressive track record, just a couple of years removed from an All-Pro season with 139 tackles, 15 for losses, 10 passes defended, two sacks, and a pick-six. He had four consecutive seasons with over 100 tackles before that streak ended last year.
Williams is known for his ability to chase down ball carriers from sideline to sideline, showcasing the athleticism needed to be a threat in the blitz game. His hits are notoriously powerful, often sending helmets flying.
However, despite his athletic prowess, Williams' style doesn't quite align with the philosophy of new defensive coordinator Christian Parker. Parker's system emphasizes sharp gap discipline and spacing, areas where Williams has struggled. Last season, he was benched by the Jets for over-pursuing and lacking situational awareness, which left his teammates vulnerable.
Williams' aggressive approach is just one concern. Parker's defense requires linebackers to excel in coverage, taking away parts of the field in various zone schemes. Williams has been a liability in coverage, frequently targeted by opposing offenses.
Reliability in tackling is another cornerstone of Parker's system, and this has been a challenge for Williams, who posted a 15.7% missed tackle rate last season. While he has the tools to be a standout linebacker, he's not the ideal fit for what the Cowboys' new coaching staff needs.
The idea of the Williams brothers leading the Dallas defense is appealing from a public relations standpoint, but it could be problematic schematically. The Cowboys need disciplined run defenders to improve their defensive efficiency, and prioritizing family ties over fundamental football could hinder their progress. To address their defensive struggles, the Cowboys require a technician, not a wrecking ball that sometimes targets the wrong structure.
