Cook is on pace to have 325 carries for the season. He is not a large guy. I know his smooth running style and body control prevents him from taking a lot of big hits, but he is getting too much work imo. The problem is the Bills entire offense is so extremely reliant on him. If it feels difficult to remove him from the field because there is such a drop off, then it calls into question another area of roster building and depth where Beane deserves scrutiny.
