Dolphins coach Tony Sparano told his players to ''stay home'' and keep out of trouble during their three days away from the NFL grind last weekend. But he could never demand each player not be tempted by trouble. And that's what running back Ricky Williams admitted happened to him, if only for a few moments. Williams, in the NFL's substance-abuse program since 2002 and having tested positive four times, said Monday he was briefly tempted to smoke marijuana while the Dolphins had their bye weekend. Williams said the extra free time was the primary reason for the temptation. ''Most definitely,'' Williams said. 'It's greater because, like, Thursday, coach told us we had Friday off, so automatically your mind, which is so constrained since training camp began -- every day is a grind, it's a grind, it's a grind -- and then Coach says `you're free.' And the mind says, `I'm free, what can I do?' ``So there was definitely an urge. But I just thought about what I have to lose and it was easy. The urge didn't last very long.'' Williams said he successfully combated the urge to smoke by meditating instead.
