Samaje Perine will battle Rob Kelley for the starting gig, and Chris Thompson has proven to be a very effective receiving and change-of-pace back.
If Jones finds a new home, perhaps his situation improves. Jones has asked for a trade, and he does not appear to be part of the Redskins' plans at RB. He is still young enough to revive his career, but that seems unlikely. As a final pick in your draft, he could be worth a roster spot until camp and preseason sorts this out, depending on who else is available to you.
