I think it is mostly age with Ricky; otherwise, they'd resign him.

Ricky: Dolphins want to move on in backfield
Free agent Ricky Williams believes the Dolphins fully intend to move on from him and Ronnie Brown in large part because there is a new offensive coordinator in place.
Dan Henning's exit may be a handy excuse, but a more realistic reason is that the Dolphins want to get much younger and much faster in the backfield. Williams will find it hard to walk away from Miami if he receives a fair offer, but he's not expecting that to be forthcoming.
