I look at your matter differently. In NBA there is an old rule called "no layup rule" that used a lot in the East Conference. Coaches adopt this rule to play their defense. The defense effort which allow other team to score a layup is considered soft and unacceptable by many old fashion coaches, Pat Riley is one of them. Players are taking pride to defend the painted area. Dunking on other team is considered an insult. Players will get retaliation if they do that...the next time they have the ball they will take an elbow or some other cheap shots as a warning. I could not imaging Blake Griffin could survive a season back in the 90s for the way he looks to dunk the ball. But today's game is faster and we don't see the traditional centers and the muscle power forwards as much as we used to. A lot of small balls lead to a lot of long shooting and open paint area for the dunk.
Mark Jackson belongs to the 90s and that was the way his basketball philosophy was built. For the fact that GSW play "soft" the pass decades, Mark tried to change it. And it works so far. David Lee was a soft defensive player when he played for D'Antoni in the Knicks. He is a much improved all round player today, give credit to Mark Jackson.
Also, in the NBA when a game is in your hand, you will slow down to let it finish. You just don't keep on scoring especially try to break any kind of record, that is an unsportsman conduct...and that will disgust other people.
