No trash-tweeting. The Warriors superstar got into hot water Sunday when he responded to some derogatory tweets with a harsh critique of his former team, the Oklahoma City Thunder, and their coach, Billy Donovan. Yesterday Durant expressed remorse, calling himself “idiotic” and “childish” and explaining that he’d sent an apology to his former coach. “I’m just more upset with myself that I let myself go that far,” he said. Oklahoma City fans now have a couple months to cool down before the Warriors visit on Nov. 22.
