For what little it's worth, I think Ayton is overrated (slightly) and Trae Young is greatly undervalued. I think DeAndre's ceiling is a modern age Patrick Ewing. But that's ceiling - I think he'll likely be a consistent 20/10 player in the NBA but I don't know if he'll ever rise above borderline all star.
He plays just a bit too upright and has average hands (at best), an inconsistent motor/focus and a poor understanding of team defense. And despite his chiseled frame, he's far from being an unmovable force down low. If we draft him, we'll probably be wishing he came with Monroe's hands and Barkley's butt. He might be our best choice because of talent/fit but I'm flabbergasted when I hear Barkley, Kellogg and Walton talk about him as a lock to be a once in a generation talent.
As for Young, I think he hit the freshman wall 6 weeks ago and the real Young is the guy we saw in December. Very few first year players can sustain excellence while averaging more than 35 minutes a game carrying the kind of load he's had to carry. My biggest concern with him will be whether he can hold up physically, I have no doubts about his ability to excel at the next level.
