It's so crazy how being bad can boost an opinion. Black's shooting numbers are not that different from GG. GG's numbers probably a little better because of more volume, but ultimately not a crazy difference given how volatile shooting is. It is a clear weakness for Black because he is actually good at other things. Some people are even burying Black for his shooting to the point where they won't draft him because of it. If GG was one of the best defenders/passers in the draft like Black no one would call shooting a strength of his. The only reason it's a strength and not a question mark is bc he's not just bad, but awful at the other things.
The difference in the way people see these two's shooting is not the actual shooting, it's being bad/good at everything else.
I agree with literally every word you typed.
