Ricky Williams agreed to a base salary of $4.35 million in signing an extension that will keep the Dolphins through 2010. That part isn't surprising. Somewhat unique? He negotiated his own deal. And after that season, he's probably done. To do what, nobody really knows. From the Miami Herald:

On Tuesday, Williams revealed to The Miami Herald that he signed another one-year contract extension this offseason that will keep him in Miami through the 2010 season, at which point he said he plans to then retire as a Dolphin.

``I talked to Bill [Parcells] about it, and we came to an agreement," said Williams, who rushed for 659 yards on 160 carries last year.

...

``It was quiet and easy." ``That's Rick," running back Patrick Cobbs said. ``The guy does stuff nobody else does. He's smart. He knows what he wants. He's been in the game a long time, so for that stuff to happen, it doesn't surprise me."

It is believed that Williams' base salary for 2010 was $150,000 more than he actually wanted.
