I wouldn't make any changes unless you can get a real stud at RB. As far as who to target, I am not really sure. I think that Addia, Henry, and Jones Drew are only going to play better as the season plays out. I wouldn't mind parting with Reggie Bush but that's just IMO. Maybe you could package Bush with one of your top WR and try to upgrade your RB. Or you do have a good bit of depth at TE. Maybe trade Shockey(his name alone has value) with one of your RB and play Winslow/Colston. As far as values right now, and I am hestitant to say this, but last time Brian Billick took over the play calling for the Ravens Jamal Lewis had his 2,000 yard season. You could get him cheap.
