I don’t know about that. He’s done just fine against other hyper athletic players. I think Zion has the edge one on one but a hypothetical matchup wouldn’t be embarrassing to Grant.
I am completely bewildered by the people on this board who think Zion is all hype, though. If you’ve ever seen him play you know he’s not one dimensional, and he shares a lot of qualities with Grant, particularly as an on the ball defender. Who knows where he’ll end up, but for now he looks like one of the few one and dones who can dominate a college game.
