​Washington Commanders general manager Adam Peters entered the offseason with multiple objectives, but his core aim was clear: rejuvenate the defense by getting younger and faster. He let aging veterans reach free agency and added fresh faces in an effort to accelerate that transformation. With so much activity on the defensive side, ESPN’s Seth Walder faced a challenge: pick a single X-factor for the 2026 Commanders, or acknowledge that the entire unit could determine the season’s trajectory. Walder ultimately highlighted a group of defensive additions as the X-factors for 2026, including edge rushers Odafe Oweh and K’Lavon Chaisson, linebacker Sonny Styles, safety Nick Cross, and Amik Robertson along with rookies like Sonny Styles. The question remains: can this collection spark the defense from a year ago, which ranked 30th in EPA per play, and lift the unit to a level that fans and coaches hope for?
The Commanders’ defense endured a tough 2025, absorbing a rash of injuries that depleted depth and disrupted continuity. Notable season-ending injuries sidelined Deatrich Wise, Javonte Jean-Baptiste, and Dorance Armstrong, all of whom were expected to be significant contributors on defense. While those players remain on the roster, their absence was felt at key moments, and the lineup now includes the newcomers brought in to compensate. The performance of Odafe Oweh, K’Lavon Chaisson, Leo Chenal, Nick Cross, Amik Robertson, and the rookie Sonny Styles in 2026 will be crucial to the team’s overall success. If these players meet or exceed expectations and if they mesh effectively as a unit, the Commanders’ defense could show a marked improvement over 2025. Conversely, failure to live up to projections or to develop as a cohesive group could leave the defense vulnerable again, undermining any headway made by the offseason changes.
The stakes are high for Peters and the coaching staff. The success of the defensive overhaul hinges not only on individual performances but also on how well these players function together as a unit. The new pieces will need to translate potential into consistent play, demonstrating the versatility to rush the passer, hold up in run defense, and cover effectively when called upon. If the group can establish a disruptive front and an agile, communicative secondary, the Commanders could see a substantial uptick in their defensive efficiency and overall competitiveness in 2026. However, if the chemistry doesn’t click or key players fail to meet expectations, the unit could lag behind the rest of the league once again.
In sum, the Commanders’ 2026 outlook on defense revolves around a multi-player X-factor: the combined impact of Oweh, Chaisson, Chenal, Cross, Robertson, and Styles, along with the contributions of the other new faces. The season will reveal whether this group can transform a historically underperforming defense into a cohesive, faster, and more dangerous unit. If they deliver, the defense could be vastly improved from 2025; if not, the quest for a formidable defense will continue. This assessment reflects the broader viewpoint that the defense’s fate may rest with how well these newcomers integrate and elevate the unit as a whole.
