I believe it was done intentionally, as to why? I have no idea, it was very strange. You could tell by the way his arm followed through that it was intended to connect. Elbows are dangerous, and obviously not welcome in the game. The NBA will be suspending him for sure and wouldn’t be surprised if they force him to sit out the first round of the Playoffs. Additionally a fine would not be too harsh either. I like World Peace, but he just obviously as anger issues. I hope he can control it, he doesn’t have too long left of his career and i’m pretty sure he’ll always be tagged for his crazy anger moments.
