Miami Heat star LeBron James has stated that he would win the NBA All-Star Dunk Contest if he took part in it.

The 29-year-old put on a show at practice on Monday which reignited calls for him to participate in the event, but he continues to refuse to do so.

"That's rare, very, very rare. We had a great practice and we felt good. When it stops becoming fun, you should stop playing. I'd win it," he said, ESPN reports.

James has previously stated that he will never take part in the contest because he is an "in-game dunker".
