The shot profile is where I find the similarity with CJ. There are few scorers in the NBA that can survive without getting shots at the rim and free throw line. CJ is honestly the only one that comes to mind but I'm sure there are others. Clarkson maybe? Again, not exactly the most efficient scorer. I'm not saying he plays exactly like these players, but I'm just pointing out how rare it is to be a good scorer without being able to get to the rim. JHS is not a 6'6 CJ. CJ is an elite jump shooter. JHS is just average, but he will need to become elite like CJ to make things work.
IMO, JHS has the more limited outcomes and is more likely because the likelihood he becomes am efficient scorer is so narrow. Even if he becomes ELITE at making the kinds of shots he takes, he will struggle to be average. George and Bufkin in particular have much more clear paths to being starters because they can produce more efficient offense. To even have a chance at being efficient JHS has to prove he can turn those mid range shots into 3 balls, and even if he can he will struggle with his awful+nonexistent pressure on the rim. You can get better at the rim, especially with NBA spacing, but IMO that is a physical limitation JHS has. He has no burst to get the rim and when he does he's a ground bound. Even with a ton of improvement he would still be below average.
His measurements are great, those measurements don't seem to help him much. He is amongst the worst in class at finishing at the rim and in stocks. If the size amounted to more I'd be interested. His PG skills might be the best of this group, but IMO George and Bufkin are not far behind. I'm harping on the scoring a lot, but that's because I think that's his path as an NBA player. He's not exactly a standout in other areas.
