Wade, James 'childish ... ignorant', says Nowitzki

Heat stars claim they were just playing to the TV cameras

MIAMI - Dirk Nowitzki said on Saturday that Dwyane Wade and LeBron James were "a little childish, a little ignorant" in a video that appears to show them mocking the Mavericks star's recent illness.

Wade said he really did cough and turned it into a generic joke because cameras were rolling. He and James blamed others for trying to make a big deal out of it.
