The best dunks from Lebron James, while on the Miami Heat. These dunks, in my opinion, are the Lebron James top 10 dunks with the Heat. The best Lebron James highlights are hard to gather because of his ridiculously long highlight reel. His slam dunking ability is ridiculous and always exciting, but I still don't know if he truly made the right decision going to Miami. Enjoy the new Miami Heat superstar and let me know if there are any dunks you think would be appropriate for this list. Enjoy the Lebron James slam dunk compilation.
