The Celtics rarely get the benefit of the calls (occasionally they have and I'm always amazed when it happens) We know that the Bulls, the Heat and the Lakers will all get a bias from the officials. I fully expect the Celtics to have to fight the Knicks and the refs. But a good team can still win even with an officiating bias. I recall the one Heat game where they took 41 free throws to 6 for the Celtics and the Celtics still won. They just have to stay focused and not allow the refs to take them out of their game.
