A $15 million average make Cook the NFL's second-highest paid running back. San Francisco's Christian McCaffrey, who signed a two-year, $38 million extension, is the only running back making at least $15 million per year. It'd put Cook ahead of Indianapolis' Jonathan Taylor ($14 million).

Bills head coach Sean McDermott has spoken highly of Cook, making it clear that the team values him. But valuing a player and paying top dollar for a running back are two different things. The Bills have cap considerations, and while Cook has proven his worth, history suggests that Buffalo might not be willing to break the bank for him.
