Ricky Williams is discussing a comeback with the Miami Dolphins, coach Nick Saban said Thursday. Saban acknowledged holding recent discussions with Williams, whose sudden retirement stunned the Dolphins shortly before training camp began last season. He would not divulge specifics of the talks, but has long said that he was open to the prospect of Williams returning. Williams rushed for 3,225 yards and 25 touchdowns in his two seasons with the Dolphins. "Ricky still seems to be very, very interested in coming back," Saban said. "As I've said before, the things that we discuss, we've decided not to talk about publicly. I think that I can safely say that you all know about his situation as I do." Leigh Steinberg, Williams' agent, didn't immediately return a phone message seeking comment.
