my gut says he's probably not. he doesn't look big enough, quick enough, skilled enough or athletic enough to make it if he can't shoot say 37%+ from three. his rookie season, on his biggest sample, he shot 38% which is encouraging. if he can get back to that, maybe he'll make it. but without it, i don't see him having a big enough impact on either end to make it.
just answering the question as honest as possible. ultimately dude is 22 coming off a broken leg so to unequivocally count him out would be dumb.
