As he's an allstar, I wouldn't train too much Jump shot and Rebounding as those two eat too much potential of a SF. I'd concentrate on guard skills the next few seasons since you already have two of those and use this rotation:
2 weeks Pressure for PG (for Outside defense)
2 weeks 1 on 1 for Forwards
And you do this until his OD is 13. Depending on what you want for your other two trainees, you can swap one 1 on 1 week for Passing or Jump shot. But in order to be an effective SF for his potential and salary, he needs a lot of 1 on 1 for Forwards.
After you're done with your guards training, you can start with his ID which should be 11-12.
Then you round him out with a bit of RB (max 9) and JS (max 10). With these skills:ž
10, 7
13, 14
15, 8
12, 12
8, 7
He didn't even touch the allstar potential, so you can train him more in skills you like. You just have to know that for each pop in primary skill (especially RB, JS...) you can get 3-4 pops in secondary skills (HA, DR, PA, IS).
