Ron Artest by any other name is still Ron Artest. Call him Metta World Peace and he’s still part thug — no way to dress that up. Today he appeared to purposely elbow James Harden in the head. World Peace said it was an accident. It looked like no accident to me. If this didn’t happen on a basketball court you’d call it assault. Harden has a concussion. What penalty should the NBA give World Peace? The league should make him sit as long as Harden can’t play, even if that means missing the playoffs. Let World Peace contemplate the meaning of peace.
