Jim Brown knows all about being the NFL rushing king. Nobody has held the career rushing title longer than Brown, who had it from 1963-84. Emmitt Smith is the current rushing leader, having set the mark in 2002. But Brown said Vikings star Adrian Peterson could top it one day. "If he wants that and he dedicates himself and he has good fortune, that's a great possibility," Brown said in a phone interview with the Pioneer Press from his Los Angeles home. "I think if he sets his goals and he understands his circumstances and he knows what it takes, that he can be successful. I'm not saying that he will break the record, I'm just saying it's a possibility." St. Paul Pioneer Press
