Javonte Williams serves as the Dallas Cowboys' lead running back in 2026 after signing a three-year extension following his 2025 career year of 1,201 rushing yards and 11 touchdowns on 252 carries. Through the first four games, the 26-year-old has already posted five rushing touchdowns on 62 carries for 231 yards at 3.7 yards per attempt while adding 15 receptions. Coach Brian Schottenheimer has labeled him the clear "bell cow" in the backfield, with the offense feeding him heavy volume in a run-heavy scheme. Key variables for his full-season total include continued goal-line work, offensive line protection, Dak Prescott's efficiency, the Cowboys' 2-2 record and schedule strength, plus any late-season workload management or injury risk in a 17-game slate.
