James Cook
The Buffalo Bills have almost completely turned over the running back position from a season ago. Last year, the group was led by Devin Singletary and Zack Moss with rookie James Cook. However, the team would trade Moss during the season and Singletary signed with the Houston Texans.
This has opened the door for James Cook to emerge as the starter with veterans Damien Harris and Latavius Murray behind him. The Bills should utilize Harris and Murray as power running backs and in those short-yardage situations.
However, James Cook is going to have probably the biggest role in this offense and should get a majority of the work at the position. He is a big-play threat at the position, both running the ball but also as a receiver out of the backfield.
The benefit of having a receiver like Cook is that it doesn't really take the ball out of Josh Allen's hands so they can run pass plays but utilize short passes to Cook as essentially run plays. It will be interesting to see where they have the second year running back lining up and if Dorsey tries to create mismatches by splitting him out wide and drawing linebackers into coverage.
