DeMarcus Cousins lost his cool and the Golden State Warriors lost at home in embarrassing fashion once again. Gordon Hayward scored 30 points off the bench, Kyrie Irving had 19 points and 11 assists, and the Boston Celtics ran away from the Warriors early on the way to a 128-95 win Tuesday night in a game that turned testy with the two-time defending champions down big. Cousins and Terry Rozier received double technicals with 8:44 to play.
