I think Stern is an excellent overall commissioner who recently can't see that he needs to address his perceived officiating problem because he's too locked into a long term future set of negotiations with the NBA Player's Association. He's so intent on sticking it to the players that he is losing focus on what is really best for the league as a whole right now. This new focus on techs is a bad ruling and it will hurt the league but it will show the players who the boss is. Kind of immature and dumb if you ask me.
As for last night's games, except for one or two obvious horrible calls, I thought the refs were great.
See, I don't think he is that blind. I think he knows exactly what he is doing. And I think there is a lot going on behind the scenes that we are not privy to, regarding the refs.
I do think he is working hard to clean up the refs, however, he also needs to work with their union in doing it. He knows that dragging them through the mudd is going to both hurt the league itself, by killing the credibility even more, as well as destroy the goodwill he has in negotiations with the refs union, which would make it tougher for him to implement stricter rules for them.
I think it is a calculated risk to take on some fire for supporting the refs, and acting like nothing is going on, while he works to clean things up from the inside out. He knows that conspiracy theories will do a lot less damage to the league, than dragging themselves through the mudd in a big scandal.
As for the new technical rules and all that, it is all part of their marketing goal of ridding the league of the "thug" persona it has taken on in a large part of the sports fan base. There are a ton of people (many of them older, rich guys, who pay for luxury boxes) who are turned off by the way NBA players are percieved, and carry themselves these days. So Stern is trying to pander to those who sign his paycheck.
It may come accross as over the top, and you could even argue that there are racial undertones to the new rules...but the bottom line is it should help the league make more money. And ultimately, that is his job to do.
