obviously was significantly more explosive and had better ball-handling skills.

It's hard to find players of AJ's size with his skill set coming out of HS outside of LeBron. The closest I could come would probably be Paolo Banchero. He was a legit 6-8 230+ as a HS senior and he already had pretty solid ball-handling and outside shooting skills. I think he wasn't as explosive as AJ, but a very, very good athlete for sure. Ben Simmons had the frame and athleticism, but was wayyyyyy behind AJ in terms of shot making.
