I don't think Bron walking the ball up in the middle of third is as significant as a attempted game winner or crucial plays during OT. and like a poster mentioned earlier, not even the crowd caught it.
but context is important, this is a league where Corey Brewer got away with carrying the ball from half court.

. traveling is the most unenforced rule in the book,
but few get away with a blatant hack on the arm.
If we were to breakdown that possession where Iggy hacked Bron on the arm - the first indiscretion is actually Bron traveling, yet we have the majority of this board acting as if that play was completely based on the refs missing the foul (whilst disregarding the travel beforehand). If that play was called correctly - it would've resulted in a Bron turnover - not Iggy being called for a foul.
it's only natural that we place greater importance on what's called in the 4th since that's when the game is decided.
The game is decided over the course of 48 mins. No quarter is inherently more important than another. And although I do understand that it's only natural to place greater importance on what goes on in the 4th, what I'm saying is that folk need to realize everything that goes in during the first three quarters should be valued equally. This is the same culture that centralizes everything based on the 3rd act, rather than the
acts as a whole.
II gave my impression watching the game in real time but perhaps you're right, if I go back and dissect and scrutinize each play from the opening tip, my opinion could change.
Take this for example -

Klay's called for his second foul in the 1st quarter [he exits the game], when he made NO contact with Shumpert's hand/arm when contesting the layup. At this point, he had nine of the Warriors' 11 points within the first five minutes of the game; the Warriors are leading and have the momentum. This mistake from the officials changed the flow of the game, which allowed the Cavs to equalize the momentum - taking away any advantage Klay and the Warriors potentially would have had in quest of extending their lead in the first quarter.
That blunder from the officials meant the Warriors went
12-13 possessions without a player that scored 81% of their points up until the point he left the game. Yet the majority doesn't wanna acknowledge the damming effect it had on the Warriors, because i) it happened in the 1st quarter ii) they're too caught up in this agenda of pushing the contrary.
And that's only ONE example of a call/non-call going against the Warriors.
