Just like last season, when he got frustrated and tried to take out Rudy Fernandez. (of course, since he was a Laker then, it was dismissed as an accident. )
Neither you nor I "know" what Ariza was thinking. But I can make an educated guess based on my understanding of the player involved, what led up to it, and what happened in the immediate aftermath. No functioning, rational person will pick a fight with someone simply because they strip the ball away cleanly.
