Byron Marshall, RB Washington Redskins

Once he arrived in Arizona, Peterson carried the ball 129 times for 448 yards and 2 touchdowns. That works out to 3.5 yards per carry (YPC), which was well off his career 4.8 YPC average. He did get a major workload, garnering an average of 23.0 touches in six games with the Cardinals. Washington’s interest in signing a running back was obviously prompted by the injury to Derrius Guice, but it’s unclear where Peterson will fit on the team’s depth chart, at least initially. Will a 33-year-old Peterson be a better option than a 25-year-old Rob Kelly or a soon-to-be 23-year-old Samaje Perine? Time will tell, but at first glance, neither of the younger players impressed in 2017 and Peterson proved during his stint with the Cardinals that he could still carry the load, albeit inefficiently. He’s not much of a threat in the receiving game, so this signing should only impact Chris Thompson’s carries, not his catches. Thompson’s role should be relatively secure heading into the regular season.

Our rankings have been updated but Kelley, Peterson and Perine are all just speculative picks at this point until a frontrunner emerges.
