But there will be lots of people training USA guards for the U21 team, so there is more "competition". If you want to get to the U21 you go with player B and make him into a SF (so you pray his OD is not too low to start). I don't know how anyone could think it is a better bet to get the PG onto U21. Sure he trains faster but will you have a superior or higher trainer to compete with all the other people trying to get onto the U21 squad? Plus who's to say you won't be "competing" against 6'0 PGs that come out with A+ skills? There is no guarantee of course but I think the higher probability clearly lies with player B. Also, what is a player position with 'Respectable' in all skills? I believe it is a PF ;)
