Reasonable minds can differ on his ceiling, but you guys that say he can't play or run haven't been to many practices. I have and over a two hour session you plainly see why Lon gave him a schollie. He can run and he is completely unafraid of contact to the point of the coaches constantly having to restrain him from illegally bullying people.
He needs a lot of work, particularly with his hands (not feet). But, he is extremely well coached with regard to rebounding and blocks out better than anyone on the team.
He gives you 100% as well, which some on the team do not.
I don't know what he will ultimately develop into, but bigs usually are the last to develop. Some really don't come on until years into their professional career. Give him some time. If he will put in Buddy/Cousins type hours, you never know. It might be a year or two even, but I think he can be a good B12 center. Who knows about any freshman (save the unusual 5 star)
