If they really believe in Shady (which they shouldn't; the eye test is clear), they may well just roll with these four again. RB isn't a position you have to draft and develop. You can plug and play same-year.
With McCoy we are going to see one more year of frustration as every other team's feature back is faster, more authoritative, and more decisive. McCoy has no juice, and Ivory has little. It would be so easy to upgrade this position, and I just don't understand why McBeane seem to be committed to being stubborn with this position. It could really hold us back.
