Denver Nuggets star Isaiah Thomas is now Zion Williamson's unofficial career adviser now -- telling the Duke star to STOP PLAYING COLLEGE BALL ASAP ... and wait for the NBA.
Actually, IT was much more to the point -- "Zion sit yo ass down lol and we will be ready for you in the big boy league."
Thomas has a real issue with NBA rules that forbids top players from entering the NBA Draft right out of high school. The rule has forced players like Zion to go the 1-and-done route at schools like Duke.
