You don’t want to have to try to guard LeBron James one-on-one on a fast break. It will not end well for you.

Boston Celtics guard Avery Bradley, who can more than hold his own on defense, was reminded of this on Tuesday night in Cleveland when LeBron completely punked him with a sick behind-the-back move that led to a highlight and an easy bucket for James.

But more importantly, it also led to this little Cavs fan losing his shit, which was pretty damn adorable.
