I agree with the shot blocking, however, his potential isn't high enough to bother about it anymore, it's too late for that.
his JS/JR ratio is off. Unfortunatly, by training JR, his JS will increase as well, and for a pure PG, I think the JS already is high enough.
Personally, I'd train him some rebounding, up 2 levels, as rebounding is used by all players and even though slightly, it also ounts for team rebounding.
afterwards, I'd train OD/HND/PASS to try to get these 3 levels equally high, and then keep improving them 1 level at a time untill he caps...
that's what I would do.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
