I hate it when sports media say things like that. This definitely isn't just an NBA thing, as almost all sports media have elements of stupid hyperbole. I get that it's their jobs to get clicks and be over the top, but it's silly.
I love Doncic as a player, but it's not like there have never been players with skill sets like his. There have been prospects with playmaking superior to his, ball handling superior to his, and scoring superior to his.
