Haha, good find. The original draft was about 3x as long.
I've (obviously) given the questions you pose a lot of thought, and my answer to it is certainly biased, not just by my fanhood, but by own experiences in large bureaucratic enterprises. No, I don't think there was a league edict put forth to Bavetta, Delaney and Bernhardt. I do think those refs were assigned to Game 6 for a reason, Bavetta and Delaney in particular. Company men don't need to be told what is best for the bureaucracy/league/organization, they already know it. Knowing and understanding those things without asking questions is how they got ahead in their positions to begin with. Any "edict" or whatever was implied in their selection to the game. It's a theory/idea certainly less nefarious than the "David Stern controls all!" concept, but it's one that still assaults the basic premise of competitive athletics.
Bernhardt's quotes in the Grantland oral history (so well done) are particularly interesting, with regards to all this:
As to your question: "Is it believable to you that it was some combination of bad angles, subconciously letting game 5 get to them, being influenced by the crowd, etc. that caused the Lakers to get the whistle in G6?" Yes, all that is certainly possible. Those things influence playoff games, and yield questionable calls, all the time. What separates Game 6 though, in my opinion, was the frequency of those questionable calls. They just piled up on one another like a car wreck, and the most notable of them (the Pollard and Divac phantom calls on Shaq in particular, the Kobe elbow on Bibby gets a lot of play but was somewhat more understandable given the angle) weren't even close. They were awful, atrocious, game-swinging calls, and they happened in multitude.
That Lakers team was amazing. Should the Kings have hit their free throws in Game 7, making Game 6 just a quirky footnote? Of course. But that doesn't change the fact that, with better (or fair) officiating in Game 6, Game 7 should never have occurred.
I'm going to go cuddle with my Chris Webber plush doll now.
