Don't be "that guy" who blames it on the officials or some sort of conspiracy theory. The officials were horrendous all night long and both teams suffered at times because of it. They didn't call some obvious fouls, called fouls that weren't fouls, realized it, and then made make-up calls that weren't fouls. It was terrible. Which is becoming pretty symbolic in a Joey Crawford officiated game. He's the definition of a "diva" referee. When refs should do everything in their power to stay out of the limelight, Joey Crawford does what he can to stay in it.
However, if you're referring to missed calls at the end of the game deciding which team won I have a feeling you're being pretty biased. There was a no call when Dwayne Wade was practically tackled by Boris Diaw after he came up with a steal that ended up resulting in a 3 pt play by Tony Parker. Then Tim Duncan pushed Bosh to the ground which cleared the way for Ginobili to get an easy lay-up. It was a pretty obvious offensive foul that wasn't called. Not to mention multiple no calls in the 3rd quarter when James was mugged trying to get to the basket.
I'm not arguing that the Heat didn't get lucky on some calls too, but it went both ways last night. The Heat ended up being the team that overcame it. Mainly because of some offensive rebounds that led to second chance points in clutch moments. It was the first time in this series where the ball bounced their way at the end of the game.
