I generally agree with that, however, when the same thing is happening in both Real and on national team, you begin to wonder. Sure, we could say that both situations are specific because he's playing next to big, ball-dominant stars in Llull and Dragic, but the NBA is truly stacked with star PGs nowadays, so he's most likely always going to play alongside some ball-dominant star PG. What if he's always going to submit?
Yes, he's young, but people's personalities don't change with age nearly as much as society thinks. Main personality traits remain the same, you are who you are in late teens, you just gain experience with age, so your personality gets small tweaks, adjustments, but nothing drastic ...
If he ends up being clearly the best player on the team (like Dirk, for example; somewhat similar personality), that shouldn't be a problem at all, but if he's going to be 2nd or 3rd best player, it could hinder his game a whole lot ...
Don't get me wrong, I really like that Doncic is like that as a person, but in most situations you need to be a bit of an arrogant **** to be a true star.
