Ricky Williams believes it is time for him to leave the Dolphins. "I can't lie," Williams told WQAM in Miami. "It's been floating around. I've been a Miami Dolphin off and on for eight years now. I was thinking about ... when I got drafted. Looking back, it's almost like there's different phases of my life. It's like when you graduate from one phase, it's an internal school of life. A lot of times when you graduate from one lesson to another lesson, you actually change locations. "This has been a long lesson. I flunked a couple times. It seems like now it's time to move on." Williams also expressed distaste for coach Tony Sparano's micromanaging style and said Sparano was more overbearing than the notoriously fussy Nick Saban. "A team takes on the personality of the head coach," Williams said. "I think the way we're coached, Tony goes through a lot of effort to show us the things that it takes to win football games: not turning the ball over, converting third downs, scoring in the red zone. He spent a lot of time saying 'If you do these things you win.' Sometimes, I feel like he does it a little bit too much. "My personal opinion is if you have the right attitude that 'You guys are going to win,' then all that other stuff takes care of itself."
