Bills beat writer Matt Parrino came away impressed with RB James Cook at OTAs. “Cook looks bigger and quicker in his second OTAs after the Bills took him in the second round back in 2022,” Parrino wrote. “He’s the odds-on favorite to be the team’s starting running back and he looked the part on Tuesday." That last part is particularly interesting (and debatable). Cook brings more big-play ability than Damien Harris, who signed a low-cost one-year deal in March. But Harris projects as a bigger factor near the goal line. And we know about Josh Allen’s rushing in close. (He carried 15 times inside the 10 last year, scoring five times.) Cook’s receiving performance will be key, and there’s at least an opportunity there. New Texans RB Devin Singletary leaves behind 52 targets -- 20 more than Cook saw as a rookie.
