By the time they get to this level, I think refs are all really conditioned to take into account the score and the situation when making close calls. And I think that is actually not a bad thing.
You see it all the time where the ref thinks he has a foul but waits to see if the basket goes before calling it. You would like refs to be certain and call what they see every time, but it just doesn’t really work like that in a fast game with world class athletes. If the ref is 75/25 on contact, it seems to be rough justice for the ref to call the foul if the basket is not made but take a pass if the basket goes.
On the Butler foul, remember that the ref thought that it was a two point attempt. That seems to be important. Not calling a foul where there is one can be as much of an injustice as calling one. If the ref thought he saw a foul and thought it was a two, the worst outcome if he misses the call is OT and the worst outcome if he calls nothing and it turns out there was a clear foul is that he decided the game unfairly.
I think refs do this kind of consequence-of-being-wrong analysis on the fly all the time, maybe unconsciously. I have posted my thoughts about this aspect of replay mostly in the context of football but it applies here too. It can really undermine these kind of rough justice calculations that refs often make and end up tipping the scales. It is worst in soccer. But it really impacts basketball too. Remember when they had these plays where the refs thought a foul was too consequential so they would just call out of bounds off the offending team even though the ball was technically off the hand of the offensive team? Replay ruined that and they had to change the rule after Booker and the Suns got screwed in the playoffs.
