Let me ask you this:
Does anyone under 30 think the NBA is ruined because it's geared towards 3's and dunks now (due to analytics and because those are the things casual fans tend to like anyway)?
No?
Well, there's your answer. The NBA is sports entertainment and the only demography they really care about these days is young people.
Nobody's going to make any sweeping changes to the game because a bunch of 40 to 60 year olds are nostalgic about the game they watched when THEY were young.
Now, I understand the basic issue of esthetics very well. I too enjoy an NBA game with variety, scoring from all over the floor (as long as it's efficient), different roles for different players and body types. There was a time when the NBA game was more like that. But the thing is – once I remove the nostalgia tinted glasses and put emotion aside, I understand that as much as I liked it, that was an inferior, more inefficient brand of basketball. The game had not been "solved" yet. Now, due to analytics, the genie is out of the bottle, and trying to put it back would destroy the whole bottle.
As I joked above, there's still plenty of inefficient basketball to watch. Plenty of bad midrange jumpers, all 10 guys inside the arc at all times, non-shooting playmakers dribbling around, coaches screaming. The NCAA is still there.
Like it or not, the current form of NBA basketball is the most highly evolved version of the game the world has ever seen. The speed is out of this world, the team defenses suffocating, the level of athleticism insane.
We can always make small adjustments to the rules but that won't really change anything. The basic form of basketball with freethrows, 2 point field goals and 3pt shots has been solved and we can't do anything about it.
Try watching an old game from the era before the 3pt arc. Terrible. Nobody can seriously say that was a better brand of basketball overall. It was simply natural evolution when the arc was added to the game, and from that point on, there was a clear path towards analytics and "solving" the game. It simply had to happen.
