Did you doubt Ricky Williams? Back in 2004, did you call him selfish? Did you burn a jersey or smash a bobblehead? Did you mock him for his personal problems? Ricky said he needed to find himself. He retired and moved to a tent in the Australian outback. He enrolled in a holistic medicine school, studied Hinduism in India, taught yoga in a California ashram, and played a season with the Toronto Argonauts. Then he came back. In 2008, he teamed with Ronnie Brown to form the "Wildcat" offense, which stunned defensive coordinators around the league. Then in 2009, when Brown went down and with a first-year starter playing quarterback, Ricky once again carried the Dolphins on his shoulders. He set an NFL record for longest span between 1,000-yard seasons at six years. Now he's one of the longest-tenured Dolphins, just a few hundred yards shy of the franchise rushing record. He won't play much longer, though — he wants to attend medical school. And if you think Ricky won't be a doctor, you've learned nothing. Don't doubt Ricky Williams.
