I agree with this plan, it seems great to me. One thing I'd like to add is I like Respectable/Strong Inside shot on Guards because it helps their Driving a lot. If you train JS enough on Wingmen position (I'd recommend at least one-two weeks also on Forwards), he will get at least two pops in IS anyway and he will rarely miss a layup.
Unlike other PG/SGs with Marvelous Driving and Atrocious/Pitiful IS, who miss at least 3-4 layups per game in inside tactis (hint hint -
