Andre Miller says he lost his cool when he and Denver Nuggets coach Brian Shaw got into a shouting match. He hasn't played since his confrontation with Shaw late during a game on New Year's Day. Says Miller: "It was just an instance where I kind of lost my cool and was a little bit unprofessional and stepped out of character. Miller spoke Friday after his first practice with the Washington Wizards. And I apologized to my teammates for what happened. That's not me. That's not what I'm about."
