Seriously, I know in hindsight it doesn't matter, but I'm still trying to figure out what the call was against Capela late in the fourth. If that was an illegal screen, then the NBA might has well make screening illegal completely. That was text book in my opinion. The Warrior player flopped going around it, but the ref who blew the whistle because of that should be benched.
Seems like refs don't make calls based on the actual play... they make calls based on the reaction of the player to the play. So if you are fighting through a screen and don't fall all over the place, they won't call a foul no matter how much of a moving screen it is. And on screens with very little movement or contact, if the defender falls down like he got punched by Mike Tyson, then the refs will call a foul regardless of how insignificant the screen actually was. Because of this, the refs actually encourage flopping.
I've noticed that the warriors accentuate contact on almost ever contact. And their fanbase is the first to call Harden a flopper.
