Parker's speed changes complexion of rushing attack

— -- DETROIT -- The catchy nickname, "Fast Willie," is a bit of a misnomer. Oh, it's appropriately descriptive enough, since Pittsburgh tailback Willie Parker, the other featured runner in Super Bowl XL, is plenty fast, having been clocked in the 40-yard dash at a breathtaking 4.28 seconds following his senior season in college. But until this season, when he won the Steelers' starting job in his second NFL campaign, Parker led more of a "hey, not so fast there, Willie" existence. Which was difficult, at times, for Parker to reconcile. "I'm not the kind of person who likes sitting around and wasting time," said Parker, who went to training camp at St. Vincent's College last summer as the No. 4 tailback on the Pittsburgh depth chart. "For me, I want everything to happen, like, right now, you know? But patience, hey, it's a funny thing. It can humble you but, in the end, it can also make you a better person."
