Michael Vick, who has worn his long hair in braids since proclaiming in 2004 he wouldn't get a haircut until he won the Super Bowl with the Atlanta Falcons, showed up for offseason workouts with a new short natural cut. Vick wasn't talking, but team spokesman Reggie Roberts said the decision was part of Vick's resolve for a clean start in 2007. "The guy is making some changes, not only in his personal life but in his business," Roberts said.
