Every game, someone different steps up for the Miami Heat. Well, someone different and that guy named LeBron. Ageless Ray Allen scored 23, setting the NBA career playoff record for 3-pointers in the process, and LeBron James had seven of his 22 points during a decisive run that closed out the third quarter -- and maybe the Milwaukee Bucks. The Heat's 104-91 victory on Thursday night gave the defending champions a 3-0 lead, with a chance to complete the sweep Sunday afternoon at the Bradley Center.
