a couple of major pet peeve calls in recent games:
1.  the foul on Austin Rivers against Durant on his OT three pointer (think it was OT).  Did the ref actually see contact on Durant's elbow?  Because on replay I could not see contact.  So was the ref guessing?  Cardinal officiating sin = guessing.  REFS:  please see contact clearly, see Durant' elbow change location for example, hear a slap, something...but DON'T FREAKING GUESS!!!
2. the foul on Chris Paul in OT when he was boxing out for a rebound.  What?  You call that in overtime?  Wasn't even a foul!  Only a whistle happy jerk would call that, especially at that time in the game.  
I'm not suggesting a bias towards Warriors in game 3.  Just terrible calls I saw in OT.  Shameful really.
