Ye i agree with Dire-wolf, training OD takes agggges and if you are looking to make him a SG both JR and OD are important, if you want him to be a PG then OD is still important but you'd need more passing.
I'd have to say though because he's 18 i would suggest sticking to things like JS/JR.OD shooting, but it also depends on who else you are training at that moment, dont neglect the fact that he is your player and you should be looking to slot him in somewhere useful so ye.
he looks good at the moment though, good job :)
