LeBron James won't participate in the Slam Dunk Contest, but this is a mini-preview of what it would be like.
LeBron James doesn't do Slam Dunk Contests. Yes, any dunk contest he participates in would be probably the most-watched since the glory days of Michael Jordan vs. Dominique Wilkins, but he won't for a variety of reasons. Chief on that list is, if he loses, it would make him look terrible, and if he wins, it would be wholly expected and couldn't possibly live up to any hype.
But man, it would be really, really, really, really, really awesome.
