Wow, nice prospect. I really like his height. Very suitable for a guard (his IS is a drawback however...).
I'd start off by bringing OD and passing up at the same time. Do one position training. The OD training takes place at PG, so it hurts to have a PG whose passing is at mediocre, this is why I suggest that you bring OD and passing together.
HOWEVER, if you're only planning to play him for scrimmage (cup games) and get his 48+ minutes training, then I'd say that get OD as high as prominent or so. That'll probably take 8-9 weeks I'm guessing (if you have lvl 4 trainer or above). Then for the rest of the season you could train passing.
Stamina and FT need some work too, this can be done during the all star weekend and during the off-season processing.
