I like that idea, because he's got speed, quickness and supposedly really good vision and balance on contact. If that's true, then I think he's the perfect backup ups specifically to Kamara. Meaning if Kamara is out with injury or needs a breather, they can use Jones the same way they use Kamara. Not saying he'd be as good, but good enough to keep the offensive game plan rolling without Kamara.
I think Edwards-Helaire has similar ability if my memory of him at LSU is correct. I think the RB unit is in good shape at the moment going into the draft. I don't think they have to reach for a RB.
