Which one is 6'11" blocks shots and hits 3 pointers? That's the guy that I want.
Al Horford.
In all seriousness, those guys are pretty rare. Towns, Porzingis, they don't come around too often. As far as I can tell, the guys with size who can defend the rim (Giles, Bolden, Allen, Adebayo) can't shoot, and the bigs who can shoot (Markkanen) can't defend the rim. It seems like Jonathan Jeanne might be the closest thing to what you're looking for, but at the moment, he's not considered to be a top pick. Some other candidates for the role you're looking for might be Rabb and Isaac. Rabb has some ability to protect the rim and has a decent stroke, while Isaac is much more of a wing than a big, but he has size and a "promising" stroke.
