He's still contracted to the Dolphins. Of course the way they're tossing away veterans, who knows, a 6th rounder for Ricky?
Ricky goes to someplace like Cleveland...a team that needs an RB and can get him cheap. It would be worth the risk for a team like that to give a guy like Ricky a one-year, incentive-laden deal at the league minimum. Plus, like was stated above, they could probably get him for a sixth-round pick.
