During an appearance Tuesday on Good Morning Football, Cook indicated that he's noticed a renewed spirit under the guidance of new head coach Joe Brady during the team's offseason, Bobby Kownack of NFL.com reports.
"It's just a new energy in the building," said Cook, who led the NFL last regular season with 1,621 rushing yards. "It's gonna always be like that, I feel like, when you have a new head coach coming in, a young one, too, at that. Joe [is] a young head coach coming in, his first year being a head coach. He's got new energy, that's how I feel like." While Cook didn't participate in any of the Bills' voluntary work open to the media earlier this offseason, he did participate in the team's mandatory minicamp and is poised to be full-go for training camp. Looking ahead, the 2022 second-rounder remains entrenched as the lead option in a Buffalo backfield that returns last year's top backups Ray Davis and Ty Johnson. In that context, Cook -- who logged 309 carries in 17 regular-season games in 2025 -- should continue to maintain steady volume and reliable fantasy lineup utility this coming season.
