In what realistic universe can we not know the players age, height and position?
normally heigth is really a unknown factor in basketball, there are so mayny player who get extra 10 cm in their player pass ;)
Position especially in the yyouth teams is at least in germany, very often far from reality because in lower competition players the good players often had to play on other positions maybe because a SG could bring the ball better then his teammates, a SF in an undersized teym play PF/C because of his body ...
But why you don't get this infos here, is an ingame decision so that you don't share your scouting informations with other players and get an advantage through it without paying money.
