We don't have 2 FB's. Rod Smith should be listed as a RB. He dropped 15 pounds to get back to RB shape.
Although seems Keith Smith has not been used much at all so far. So they could release him, and use rob as the FB if need the very few times they would need a FB, or want a FB in.
A few players will need to go soon.
When Moore returns. I guess Benewikere or J. Elliot or Price could be released, but why not still see what they can do. Though I think J. Elliot stays until Hitchens is ready to return.
Then when Irving return too. My guess is 2 of Benewikere, Price, eventually J. Elliot, but if they put K. Smith in that mix, I may be ok with that.
