Everyone could see that Giannis was tall, long, and athletic - but game tape of him playing against a bunch of 6-2 guys in a lower tier Greek league led teams to worry that his skills wouldn't translate. Then, post Giannis, teams took flyers on guys like Bruno Caboclo and Thon Makur, hoping they would be the "next Giannis" - but they bombed.

Add in the fact that sometimes when you pick an international player, their contract situation might result in them not being able to come to the US for two or three years, and it leads to some of them falling farther down in the draft than they normally would.
