Yeah it seems, especially on his midrange pullups, that he hangs and shoots almost fading backwards. Taking too long and poor balance. He's taking too many contested shots in general, and doesn't have a great ability to separate (or the length and athleticism to shoot over the defense), so he's compensating with this poor form. It's probably fixable with film work, shooting work, and a different role/scheme that puts him in better situations.
It's hard to know whether I'm hung up on wanting him out of HS, his pedigree, his awesome name... or definitely all of the above. But I do want to try and fix him. I'm not sure if we're able to land a better option we don't have to fix, but we've struck out so far.
