If you ever find yourself pondering the vicissitudes of Ricky Williams’ career —four times a 1,000-yard rusher, four times a violator of NFL drug policies — it’s worth considering a telling paradox: this is a guy who was cool with posing in a wedding dress on a magazine cover but refused to remove his helmet when meeting the press. On the heels of his second positive marijuana test in 2004, Williams retired to pursue holistic medicine, only to return in 2005. He then tested positive again the following year and fled to the Canadian Football League. Having purportedly kicked his weed habit, he’s now back in the NFL with the Miami Dolphins, though the former Heisman Trophy winner’s star has dimmed considerably.
