At the rim, yes I think so. From 3 it remains to be seen. But I like that he shoots pullup 3's instead of pullup 2's. He would have to be elite at mid range shots to be efficient and just average from 3 to be efficient. I don't want to give off the impression that I think his 3 ball (especially off the dribble), is a for sure thing. I never thought that....but if it is, yeah he's gonna be tough to handle. The appeal of Cam is that if answer to can he shoot turns out to be "yes" he's likely a star. If he can't shoot at all he might end up like Okoro, but I think he will at least be able to be a good spot up threat (his #'s were very good) which makes him a dynamite off the ball player. With Cam you're really drafting him for that special speed+power combo which is special an unique IMO.
There are similar questions about the other players in the same draft range. If you could tell which one of Cam/Scoot/Twins/Jarace/Black it would be easy to tell who the star will be

You have to go down to Hendricks to get a guy who you are fairly confident can shoot, and that's why he'll likely go ahead of some in that group.
