Who Should I Start? Jaylen Warren or James Cook

Pittsburgh Steelers running back Jaylen Warren had the best fantasy finish of his career in 2025, and he could take another step forward with less competition next season. Warren entered the 2025 campaign as the Steelers' preferred running back after Najee Harris departed in free agency. The expectation was that Warren would gradually lose touches to Kaleb Johnson, but instead, he found himself in a split backfield with Kenneth Gainwell. While sharing touches with Gainwell, Warren tallied 958 rushing yards, 333 receiving yards, and eight touchdowns. He finished as the overall RB17 in full-PPR leagues, while Gainwell was the RB16. Gainwell is expected to hit free agency this offseason, and early rumors indicate that the Steelers don't plan to re-sign him. Presumably, they'll bring in another running back or give more touches to Johnson. However, as the incumbent starter, Warren should maintain a heavy workload and fantasy relevance. He has shown an ability to produce as a ball-carrier and pass-catcher, and he flashed a nose for the end zone by doubling his previous career-high touchdown total. Warren is a solid hold in dynasty leagues, and he projects as a mid-range RB2 option in redraft leagues for 2026.

Buffalo Bills running back James Cook III solidified himself as one of the NFL's best running backs in 2025, racking up 1,621 rushing yards and 12 touchdowns on 309 carries across 17 games. The 26-year-old also impacted the game as a receiver, hauling in 33 receptions for 291 yards and two scores. Cook III has always been an efficient player, but he was able to reach new production heights in 2025 thanks to an increase in workload. After logging 239 touches across 16 games played in 2024, Cook III recorded 342 touches in 2025 and still averaged a highly efficient 5.6 yards per touch. Cook III signed a four-year extension with Buffalo before the start of the 2025 season, so he's locked in as the team's lead rusher for the foreseeable future. The Bills also promoted former offensive coordinator Joe Brady to head coach, so it seems unlikely that the team would radically shift its offensive approach going forward. Now that he's proven he can handle a significant workload, Cook III profiles as a high-end running back option for fantasy managers in dynasty formats.
