Think the Dolphins plan on rolling with Daniel Thomas and Lamar Miller, which is why they let Bush walk. Bengals need a compliment to Green-Ellis, which wouldn't be Ivory.
Atlanta needs a big back, but obviously we have no desire to face Ivory there twice a season.
Green Bay are probably favorites for Jackson and wouldn't trade a draft pick for a RB anyways.
Colts could probably stand to add another RB.
Jets need one
Rams could use one now
