I thought in the first half, the game was slanted a bit in favor of the Celts. The Lakers weren't getting the same benefit of the doubt that we were, on either side of the ball.
In the second half, as many predicted, that dynamic shifted, with the Lakers being the beneficiaries of the borderline calls.
Overall, the game was probably on balance officiated slightly in the Celtics favor, but not enough to make the difference. The Lakers got beat because they played very poorly from midway through the first to midway through the fourth.
