Many of the posters are responding to things you didn't even say or suggest. You didn't say Zion was a bust, you didn't suggest that he was one of the worse NBA drafts, you didn't even say he wasn't an excellent player.
From my experience, the media excitement about Zion was huge. Only LeBron has as much. Even non basketball fans were excited about seeing Zion's first game. The non-sports news was covering him.
He fell radically way short of expectancies. People severely over rated him. You are right about that. Ja Morant certainly outplayed him in their last game.
( His Duke team didn't even make it to the final 4)
