As in, he’ll cuss your ass out without even thinking twice: “Sources within the Clippers organization told Starting Blocks that owner Donald Sterling went on a profanity-laced tirade inside the locker room and threatened to trade the entire team. Too bad the trade deadline has passed. Sterling, according to the sources, blasted players by name, including the team’s second-leading scorer Al Thornton. In one exchange, Sterling called Thornton the most selfish basketball player he has ever seen. When Thornton asked coach Mike Dunleavy (who was standing nearby) how he was playing, before he could answer Sterling told Dunleavy to ‘shut up’ according to one of the sources”.
