Yeah, not to be hyper critical but he looks slow, soft and sort of heavy to me. That's to be expected if you're 40 years old but for a kid to look like that worries me from the sense that that player will always be sketchy on the defensive end.
Let's also be mindful that he's 7'. He's not supposed to be as agile as a SF.. his upside is ridiculous.. we'll see if he puts in the time and has the 'tude.
(btw, my only concern is he needs to develop more killer.. he fancies himself a bit too finesse for my liking.
