Williams is cast as the lead back, with Sanders and a rookie in reserve. The backfield’s success hinges on offensive-line resilience and play design that leverages Williams’ power and burst. Williams’ workload and efficiency could set the tone for Dallas’ entire offense in weeks 1-6.

Williams arrives as a potential backfield engine, but his 3.6 yards-per-carry last season and the new cast create a high-variance situation with Blue as a rookie wildcard and Sanders as a veteran floor piece.

Williams has surged to the top of Dallas’ backfield depth chart during camp, with his bruising running style and vision laying a strong foundation for a lead-back role. He’s praised for his professionalism and smarts, and the staff has carefully evaluated him in joint practices and exhibition games to gauge his ability to handle starter reps. His performance in August could push him into a bell-cow-like role, depending on Sanders’ health and Blue’s availability.

Williams adds veteran depth behind the Cowboys’ developing tandem; his presence could temper Vaughn’s early workload while Mafah and Luepke compete for snaps. In the trio of preseason games, his usage could hint at how the Cowboys value experienced backs in a thinner room.

Javonte Williams is vying for the lead role in a competitive Cowboys backfield alongside Miles Sanders and rookie Jaydon Blue. Each of these players has faced challenges in the past, raising questions about consistency.
