The first clip, somebody pointed out could be defense related, but I still think that's a lazy effort. The best chase-down-er in the NBA doesn't need to take himself completely out of the offense like that.
The second clip is a non-story. Nothing going on there except a turnover and some overreactions from the audience.
The third clip is really bad. That's how I act when I want to send a message that I'm disgusted about the selfishness that is ensuing in a game. And as childish as that is of me, I only do it when I feel I'm right in that assessment, and I don't think LBJ is right here at all. His teammates just got a great look at a bucket playing 4 on 5.
