For a guy who is never going to do the dunk contest, LeBron James is really good at the whole dunking thing.
He had a couple of monster ones as the Heat beat the Thunder and showed them... nothing really. If these two teams meet in the finals again (a distinct possibility) this game on Christmas is not going to send any new messages that were not already known.
Among the things that are known — LeBron is really good and can dunk like few others.
