Ricky Williams readily acknowledges that his retirement might not be final.
"The easy answer is I've moved on," said Williams, "but the one thing I've learned about myself is, 'Who the hell knows?'" It's hardly rare for a veteran coming off a playoff loss to lean toward retirement only to reverse course in July or August. Williams' retirement may be due in large part to a text from Bill Parcells reading, "Don't chase this thing too long. You can contribute in other ways."
