Shaquille O'Neal weighed into basketball's great debate on Tuesday when he backed a young Michael Jordan to beat LeBron James one-on-one -- but added that both were outshone by the legendary Dr. J. O'Neal, visiting Hong Kong to promote an energy drink, faced both Jordan and James in their prime and when asked who would win a hypothetical match-up, he didn't hesitate. "Mike," said O'Neal, winner of four NBA titles with the Los Angeles Lakers (2000-2002) and the Miami Heat (2006).
