Will he take his job , rather career seriously ......meaning putting in the gym hours,  practice with correct attitude ....learn defense....this is hard of 90 % of the male population his age are less than ready to go out in the world IMHO .   It's a big step for him. 
The table is set for James Young .....he has everything he needs to succeed .  Money, coaches, vets, good GM , everything .
Will his brain develop , and maturity show up to take advantage of his gifts.
