That is completely disanalogous, given that there are two jump shooting ratings
So because of this we can readily dismiss the fact that the general population seems to ignore one of them? I have, multiple times, read in this forum that "JR 9 seems to be enough for just about anything".
(moreover: JR and IS are not parallel at all: the impact of JR on salaries makes me believe that it wasn't meant to be trained as high as IS).
You don't give team orders based on the suggested position of a player, right? Why would you then pay so much attention to how salary is calculated, given that salary is basically what determines positions?
A better analogy would be something like JS arund 14 and JR around 11 which gives roughly proficient ratings.
This still doesn't explain your conclusion that the two ratings do not correspond correctly. The fact that people train and field guards that are 14/11 instead of 11/14 doesn't mean that the system is broken.
Why is it a better analogy? Because it roughly correlates (modulo matchup issues) to the same scoring effectiveness relative to a fixed level of defense.
Sure, if you ignore everything else the game engine is doing (offensive flow, defensive adjustment, etc).
