In flex and triangle, he’d be better, especially if he had good passing teammates. Motion and FB tends to need guys to be able to “create their own shot” a little more, so that low BH hurts him.
The bigger issue overall, I think, is distribution. He is getting too many looks. I agree with slam that -2 is extreme for a 70/70 speed guy, but if he’s taking some 3’s, he can’t be one of the guys you’re leaning on for scoring. He doesn’t have the skill set to be that guy yet. Probably by conference time next season, he’ll be that guy for you, just judging by how his development has been going, from a ratings and IQ standpoint. Once his IQ is closer to A-, and his speed/per is closer to 80 with BH closer to 60, you’ll see the kind of player who can be a leading D3 scorer. Right now, he’s a 3rd option at best, if you want efficiency and wins (and *some* 3 pt threat).
