‘The Bills lost running back Damien Harris to a concussion a couple weeks ago, and have been splitting the backfield entirely between James Cook and Latavius Murray. Cook is averaging 4.8 yards per carry and has improved his success rate as both a runner and receiver this season, per Pro-Football-Reference.com, while Murray is at just 3.6 yards per carry and is down to a 45% success rate, which is his worst mark since 2018.’
