James Cook’s Hefty Load Sets Buffalo Bills at Risk

The Bills signed running back James Cook out of Georgia with expectations that quickly turned into a heavy workload experiment. In his rookie season Cook saw limited action—only 25 % of offensive snaps and 110 touches for 687 yards—while sharing duties with incumbent Devin Singletary. The tide changed in 2023 when he took over as the primary back, racking up 281 touches, and he maintained a high volume of 239 in 2024 before exploding to 342 touches in 2025.

That 2025 season produced some of the most imposing numbers in Bills history: 309 rushing attempts (the eighth‑most for a single season), 1,621 yards on the ground, and 1,912 yards from scrimmage, placing fourth in the NFL. Cook’s workload was so intense that he missed the meaningless finale against the Jets, yet still finished fourth in the league in scrimmage yards. At age 27, the concern now is whether a running back can sustain such a punishing schedule for the length of a four‑year contract.

Comparing Cook’s Workloads to Bills Legends

Historical perspective underscores how rare Cook’s 2025 season truly is. LeSean McCoy’s busiest year with Buffalo came in 2017 when he carried the ball 287 times, while Fred Jackson’s peak was 237 carries in 2008. Marshawn Lynch topped out at 280 in 2007. Willis McGahee became the last Bills back to exceed 300 carries, doing so with 325 in 2005.

Cook’s 342 touches rank him fourth‑all‑time for a single season, trailing only a handful of legends. Thurman Thomas set the franchise mark with 355 carries in 1993 and followed with 312 the year prior. O.J. Simpson and Travis Henry each logged two seasons over 300, as did McGahee, Antowain Smith, and Joe Cribbs. In just ten seasons have Bills rushers broken the 300‑carry barrier.

Performance wise, Cook put up back‑to‑back big games in December, averaging more than 110 yards per contest. He erupted for 107 yards against the Patriots, followed by 117 against the Browns, and added another 117 in the playoff loss to Denver. Those efforts helped him finish fourth in scrimmage yards despite missing the season’s final game.

Can the Bills Keep Cook Fresh for a Long Season?

Coach Joe Brady acknowledges the mounting toll, noting Cook’s ability to absorb hits and maintain his role without a predetermined carry count. Brady also expressed a desire to rotate in Ray Davis, Ty Johnson, and Frank Gore Jr. after seeing how Cook’s dominance limited those backs’ opportunities.

Davis’s workload took a sharp downturn this year. In 2024 he ran 113 times for 442 yards and caught 17 passes for 189 yards. In 2025 his usage dropped to just 58 carries for 285 yards, plus ten receptions for 86 yards. Johnson has remained a third‑down threat, but the coaching staff may need to rebalance the attack if the Bills hope to sustain a deep playoff run.

Offensive coordinator Pete Carmichael warned that workload management will be a week‑to‑week consideration, stressing the importance of not over‑exerting any single back. He cited his prior experience with Mark Ingram (career‑high 288 carries) and Alvin Kamara (296) in New Orleans, where both players stayed healthy through multiple seasons.

James’s brother Dalvin serves as a cautionary example. The younger Cook earned four straight Pro Bowl nods from 2019‑2022 while averaging 311.2 touches per season for the Vikings, yet his career ended prematurely after brief stints with the Jets, Ravens, and Cowboys, and he left the league before his 29th birthday. Health concerns loom over James’s own four‑year contract extension that began this season.

The Bills now face a critical decision: leverage Cook’s current elite form while preserving his long‑term health, or distribute carries more evenly to guard against a potential injury that could derail a playoff push. The balance between immediate success and sustainable durability will shape the Bills’ trajectory for the coming seasons.
