Its not so much the shaking hands part. I think everyone has stormed off the court after a tough loss. Its his reasoning behind it. "I'm a winner, I'm the MVP." Lord knows, that if James his circus clowns had been winning those games, we would have seen some of the most pathetic celebrating, and staged clown acts on the sidelines in history. And its only going to get worse now that Shaq is in town. To put it short, he stormed off the court because he couldn't face the agony of defeat. Owning the best record in the league, and getting taken to the wood shed was a total embarrassment for James, and he should admit that.
Also, "Nike don't allow video footage of scrimmages." Yeah right. Only when their poster child gets stuffed through the rim. Good thing for phone cameras.
