I saw this the other day and it hasn't improved much on second reading.
I don't see a lot of what Scott is talking about actually happening, particularly the unsportsmanlike stuff, though I do think they are getting better policing moving screens, which interestingly is seeing screens being set &/or used better, since the problem is most often caused by the dribbler/cutter not taking the defender onto the screen.
However, I am really struggling with 'make sure we don't just react to contact' and 'making the call too quickly'. I'm hearing that as the refs being instructed to make subjective judgements about effect, which I see as one of the problems because it complicates the decision-making process.
And a call/no call has an impact well beyond the particular incident or play.
The rules provide for five illegal contacts/plays [fouls] per game for any player before s/he has to leave the game. Fail to call one and that player has opportunity for six illegal acts, and so on.
Upshot of that is that it is common to have players who violate the rules multiple times but, because calls are missed or the officials make decisions not to call the illegality for whatever reason, are still in the game when they should be back on the bench considering how they might play within the rules in future.
So while an illegal act might not have a direct impact on a specific play, failure to penalise that illegality with a foul as per the rules means the player is able to stay in the game when s/he shouldn't be there, according to the rules, and that certainly has an impact on the game even if the specific act in the particular play phase is considered 'inconsequential'.
As I've said previously, the rules - including the provision for a limited number of fouls - are written to ensure a fair game and there is a lot to be said for sticking with them, including calling all illegal acts the officials are able to see.
The players will soon change the way they play and the coaches what they coach if the infringements are called consistently, rather than let go for fear of the official being 'too quick' or some other reason.
