Scal was on the Vertical podcast with Chris Mannix and talked about what he looks for in draft prospects. For him it basically comes down to separation. If you can create separation, you can be successful in the League. He said Maker couldn't create separation against weak high school competition. Scal's a pretty astute basketball mind, so I trust his opinion on this. The same thing he sees might be why most scouts are so down on Maker as a prospect.
The whole podcast is worth listening to, but the scouting stuff starts and about the 25:00 mark

Just listened to it, I wouldn't put too much stake in what Scal has to say on Maker.
"Whose this guy, uh Maker, Von Maker?"
The way that sounded, he's never seen this guy play. He didn't even know his name. Sure he knows "of him" (vaguely) but didn't sound like he really knows anything about him.
Also the reason he doesn't like Maker is because he said doesn't create separation, but also said Ingram doesn't separate much.
Unrelated to this, but at the end of the podcast they're talking about players calling out teammates. Scal said guys like Bird and Jordan didn't care what their teammates think, but a guy like LeBron cares what other people think. Then he goes on to talk about the '08 team. Said Pierce didn't care, he knows Rondo didn't care (big laugh from Scal and Mannix), KG cared, Ray was hard to gauge. The way he delivered that line about Rondo part had me cracking up. (That whole conversation about caring starts about the 50:11 minute mark).
