Yes, I get what youre saying about craft, but thats not the case with JJ. His fouls arent touch fouls, they are, for the most part, bad fouls. Yes everyone fouls, I get that, but hes just very good at it.
I think JJ has all the athleticism, size and ability to be a great defender and possibly player, but that is something we havent really seen from him. I dont really like using the word lazy when describing an athlete, especially one who doesnt look lazy at all. But JJ plays a lazy defense. Im not going to say all, because he is a hell of a shot blocker, but a good amount of his blocked shots come from him getting beat by his defender or being in the wrong place at the right time(and I hate using this word too, but getting kind of lucky) that resulted in a block from behind
