In a draft like, the problem isn't him at 8, it's Castle at 4 because if you're going to take a project with the latter, it'd be nice to have a baseline level of certainty with the former.
They won't even have that by selecting someone who compares favorably to this illustrious list: Exum, Ntilikina, Culver, Daniels (too soon), Black (too soon) and to a lesser extent (more true PG's) Payton, Mudiay, Dunn, Hayes and (more wings) Winslow, (Stanley) Johnson, (Josh) Jackson.
This is shaping up to the be the '22 draft redux, only with greater stakes because the picks are higher and they have one of the GOAT prospects. They screw this up, heads needs to roll.
