I think Williams could be the back who rotates in for a series and then is used to finish games. I don't really see a role for Sanders, if we draft an RB or two. Ideally, we'd get two backs better than where both are at this point in their careers. I think I'd even rather see Deuce be given a shot than two backs who both were under 4 per carry not just last year, but the last two years.
We went that route last year with our FA RB choices, and if we didn't have Dowdle, it would have been even uglier.
