what a superb rookie, start training big man skills now if u want him to make the U21 side
and keep the big man skills balanced (IS, ID, rebound, block) all within 5 levels of each other with block being the lowest.
if u want, u can train passing to respectable at most while hes still young, then concentrate on big man skills the rest of
the way. he will prolly still make the U21 side even if u do that.
play him for 48 mins at PG in a scrimmage game and train 1 position passing for about a month.
