Just read this on ESPN Insider: http://insider.espn.go.com/insider/rumorcentral?sport=nfl&incoming=1 Mar. 19 - Several people close to Ricky Williams believe the retired Dolphins running back might be considering a comeback to the NFL, the Miami Herald reports. Williams who continues to take classes at a school for holistic medicine in Northern California spoke with coach Nick Saban last week and said he stopped smoking marijuana more than a month ago. Williams also is expected to stop his legal battle with the Dolphins over an $8.6 million judgment the team has against him for breach of contract. Saban has left the door open to Williams' return since taking over as coach in January, saying he is interested in Williams if the former player has ''value'' to the team. Whether that value is by way of trade or on-field performance is not clear. Under terms of the NFL substance abuse policy, Williams can't return to the Dolphins until July or else he would face a one-year suspension from the league. As it is, Williams may still face a four-week suspension and a four-week fine of his salary if he comes back.
