I'd take him if he's in range.
He is sort of similar with Fab as he's still figuring out the game, but like Fab, he has the physical and athletic tools to be successful. He's by far a bit ahead when it comes to his post moves. Willing defender and runs the floor well.
The question is will we be okay with having two project big guys (who are big) or should we draft a sure thing.
I like him personally, I think he's more than ready than Fab is coming in. Sure he still has A TON to learn but unlike Fab, I think his feel for the game is better.
And as for developing bigs w/o Clifford Ray, why not hire Chief? At worst he can teach the kids how to use their big bodies to be relentless on the boards and be a defensive stalwart. Having two 7 footers with the ability and potential to dominate defensively may need a teacher who knows how to play defensively. Then let KG teach them to post up.
