The Golden State Warriors spat out a 17-point lead and lost, 92-88, in Boston Thursday night, in a game that was taut if not particularly elegant, and in a game that elevated the Celtics to a place that makes them the new heir apparent to the heir apparent. The Celtics have been a difficult out for the Warriors during the Brad Stevens Era, losing six of nine but only being blown out twice, and Thursday was not one of those nights. The box score will tell you the shooting and rebounding problems, but the Warriors had that lead and didn't hold it.
