Yeah, Doncic is already looking like what I thought he might be - basically, bigger than advertised, slower than advertised, skilled but not athletic. Yes, he will likely be a contributor at the NBA level... decent or even good, perhaps... but not "game changing" or even particularly extraordinary. He is a good passer for a big kid, and an okay shooter. He isn't going to be schooling NBA defenders, and is going to be a below average defender.
What he is NOT is Magic Johnson and Larry Bird rolled into one. Maybe a huskier Toni Kukoc with more playmaking ability.
