Hey mate,
belated welcome to the game.
Looking at your trainee, I would work between single position (PG- Pressure) and duel position (1 on 1 Forwards SF/PF) for this guy. His Atrocious JS is a deep concern along with low Driving making him a low scoring threat. If you train up his OD he should also pop in his ID at some point as well.
I think you could end up with an ok balanced guy, I would get him able to stay on the court defensively (I'm a defensive nut job though) and then go hard on getting his JS out of the gutter. You can afford to do this in the league and take your time, should take about a season and a half and I think you will see some decent rewards, he will be a good learning trainee for you and if you come across a better prospect along the way, this guy can slip back to your secondary option.
