It's not comical. If teams were able to generate 100% of their offense as dunks on cuts or in the pnr they will. They cannot do it. There are limits to what an offense generates for its centers... Those are limits of execution, limits of the defense actually preventing you from doing what you want, limits of the system itself, limits of the offensive skillset of the player, etc. I would be shocked if Gobert ever has significantly better offensive production than he did last year. Unless of course he expands his game. With the offensive skill level right now he is extremely limited in what he does and just how much more he can do. Here's the distribution of his offensive possessions by play type:
-ISO 1.8%
-transition 7%
-PnR 21%
-postups 4.2%
-spot up 1.3%
-cuts - 30%
-pubacks 21.8%
-Misc - 12.8%
The bolded ones are some of the most efficient possessions in basketball. If the Jazz wanted and could create more of them for Rudy they would simply because it would be stupid to not give a highly efficient finisher in those situation all the opportunities to finish high efficiency shots for the team. Those account for 80% of his offense! Misc are weird possessions they don't know how to qualify and most centers have about the same number and they are very low efficiency possessions. So that makes it 93% of his offense accounted for and extremely hard to increase the output in. This is what I mean - the rest are the on-ball possessions(isolations and postups) and spot ups. In order for Gobert to increase his offensive output, he needs to expand his offensive skillset to include more possessions in those areas. Otherwise it's not going to happen simply because he's already one of the best centers in the league finishing in transition, pnr on cuts and putbacks. There is very very little possible improvement he can make in those areas, he's already extremely efficient in them. The one area he can realistically improve is his FT shooting.
So to summarize. If we want Gobert to improve his offensive production the 3 areas are:
-off-ball offense(created by others or putbacks) - he's already at the top in those! Extremely hard to go even higher and extremely hard for an offense to generate more looks of this sort.
-on-ball offense - he needs to expand his game for this one to generate increased offensive production
-FTs... this is the only realistic one.
