He's a great trainee, imo. Driving and handling need to be improved, as does passing. Rebounding is OK at respectable, but IS/ID need a lot of work.
I like to create mismatches, so I'd train his IS until it was 12+. JR should be improved some, but I wouldn't get carried away.
For me, he'd be perfect like this:
JS: 12+
JR: 6+
OD: 10+
hand: 5+
Dr: 7+
Pass: 8+
IS: 12+
ID: 10+
Reb: 7+
SB: 3+
