Looks like a nice SF-prospect. I would go for Rebounding up to 10 or so. Then finish his inside skills (ID/IS) up to 10 or so as well. Once you're done with it I'd work on his outside skills (you can do it vice versa of course). OD up to 13, passing up to 10, JS/JR something like 12/9.
Maybe you want to check out the potential calculator and see how he could look like in the future and make a training plan afterwards.
