I tend to think the point you touch on that is most accurate is that the system favors the on ball kids that can create their own shot and draw attention via offense. The Meleek Thomas’ of the world, the Jasper Johnson’s.
I watched some Abraham in HS and he was generally a team kid, took the open 3, played defense. He was not putting the ball on the floor and trying take his guy off the dribble with a lot of iso. There wasn’t a ton of wow factor in his on ball. That said there are some visible aspects of his game that you just can’t bypass when assessing: his ridiculous hops/athleticism, his size/strength and perfect shot mechanics. He also plays in a very controlled and efficient manner. It’s hard to teach these things, and this is as a freshman. I’d expect this kid to break out in a major way as a sophomore/junior.
