I don't think that was ever a debate.90's NBA-level officiating. I'm actually having doubts that this Warriors team could beat MJ's Bulls. They were taken out of their game by the Cavs physicality.
But yes, the refereeing was atrocious. There were more replay reviews than a typical NFL game, and the Cavs were committing all sorts of ticky tacky fouls that went uncalled.
That said, you can't fault their shooting. They looked like the Warriors out there shooting.
