Days before the 2012 NBA playoffs, the ironically named Metta World Peace celebrated a dunk by committing a class three felony on Thunder guard James Harden. Though he'd later claim that the violent elbow was "accidental," the video shows a pretty clear draw back and follow through. Even more inexplicable is World Peace's reaction after hitting Harden, which was to parade down the court as though nothing happened while the concussed Thunder guard collapsed to the floor. The personal image that World Peace had seemingly worked so hard to rehabilitate was completely tarnished. In total he was suspended six games and lost nearly $500,000 in salary and fines.
