but the issue I keep pointing to — that you keep neglecting — is what sort of underclassmen in HS in the 6'4 range have the ball handling & shooting he had?

Hardly anyone.

You'll see 6'4+ kids w/ those skills as Jrs & Srs, but 6'4+ Soph & Frosh (in HS) are almost always paint roamers (if not stiffs on top of it). This of course gets at the heart of why Caleb is toying with 4 stars as a recruit.

But to say that most 6'5ish Sophmores (whatever their skillset) fill out in the way that Caleb did — that's also not accurate. Most do not end up being yoked like he is yoked--& barely outa HS. And yet he still has those perimeter skills too — & has a level of explosiveness to his game that's also quite rare for a kid of his height & bulk.
