When things are going well for LeBron James and the Cavs, it looks like they're having more fun than anyone in the league. There are 70–foot outlet passes, buckets from all over the floor, strange role players overachieving, and gamest being broken wide–open. At the end of those fourth quarters, LeBron radiates the sort of carefree cockiness that makes sense for one of the best players the NBA has ever seen. The rest of the team is laughing and launching threes, and everything looks way too easy. It's great.
When things break down, it all goes the other direction.
