What you are suggesting is completely unbased in reality and completely based on numbers and formulas. I hate that idea. I want a bball sim not some meaningless number puzzle with no relation to real basketball whatsoever. If you make a guy like you suggest, he will have no real world equivalent, and be broke for the GE and that is a good thing.
I forfeited the idea of BB being close to reality a long time ago

Now I take it as a challenge to exploit GE and salary formula.
Look at this game, for example:
(59706575): My SG was so overmatched it wasn't even funny (34k player against 166k player). But despite having JS 13 and DR 15 (and PA "only" 12), he had a very quiet game offensively because other players around him had much greater chance of success in offense. He was a monster on defense though

So as I see it, you can tell GE "Listen GE, I have this player here, he's no good at shooting, so don't make him shoot too much ok?". THe only trick is how you build him and how you build the players that surround him.
