Honestly, if we take the small sample that is the first few games of the season what he's doing doesn't really happen at any age. Guys just don't put up numbers like that in the top leagues over there. I remember when Ginobili was the big star overseas, he was getting something like 16-17 ppg. And that was great.
It really is incredible how Doncic has started the season.
His Euro League play will obvi go down(He's PER 39.2 right now), but after the first good game the opponent's coach MUST try to find defensive assignments that work especially against Doncic and apparently they couldn't.
His Domestic league performance is still really good. He's more of a distributor there and doesn't have crazy high usage, which could indicate that he's playing down to competition or the other teams can match up against him better.
