James Cook pulling away from backfield mates

Joe Buscaglia of The Athletic says that Bills RB James Cook has "separated himself" from Damien Harris and Latavius Murray in training camp, furthering the notion that Cook is headed for the clear lead role. Buscaglia adds that Murray is pushing Harris for the No. 2 job with a good camp, while Harris has also dealt with injury. Buscaglia also throws in that RB Nyheim Hines was a "borderline favorite" to be the Bills' No. 2 before suffering his ACL tear. That's especially interesting because Hines garnered only six total carries and nine targets across nine games with the Bills last year after arriving from the Colts via trade. The Hines bit plus the Murray praise could signal an iffy outlook for Harris, who signed for less than $2 million on a one-year deal in free agency. Harris has already moved down our RB rankings since the start of training camp.
