I'm not sure if I've ever heard of soft cap depending on potential and I'm not really sure if I understood the 2nd item, otherwise excellent post! Lots of extremely relevant info's!
No worries Bern. Yeah like a said these aren't my ideas these are just my accumulated research across the discord, top tier manager conversations through BB-mail, and the forums.
Training any skills above all others will always cause a soft cap to training, I think that was the gist of that soft cap, but the elastic effects are as follows.
JS> accelerates driving and inside shot.
JR> decelerates jump shot and rebounding.
OD> accelerates jump range, handling, and decelerates inside shot.
HA> accelerates outside defense and passing.
DR> accelerates jump shot.
PA> accelerates handling and driving.
IS> accelerates inside defense.
ID> accelerates inside shot, rebounding, and shot blocking.
RB> accelerates inside shot.
SB> decelerates inside defense.
Hope this helps.
