Boston fans/Warriors haters can't stop whining about the officiating. While I wouldn't qualify the officiating as 'good', I think most of the complaining is about how physical they're letting them play moreso than it is being bad. The Celtics are actually benefitting more, but failing to take advantage at the free throw line and failing to rise above the physical and chippy play mentally instead focusing on being upset and letting it get under their skin.
This Warriors dynasty is so entertaining to watch. Hope it goes to Game 7.
