It's a minor difference he's not 6'10. He's been measured at 6'9 in shoes but I wouldn't be surprised if he wasn't a little bit smaller. His wingspan's decent at 6'11. A PF/C he isn't.
The thing that impresses me most about him is his speed in the open court. His acceleration at his size is ridiculous. One thing I didn't like watching him is how he so often had to grind by defenders at the high school level. A lot of times it didn't look easy. Defenders were able to apply a lot of pressure on his attempts. Right now, he looks like he might be an all-offense, no defense big, which isn't so hot.
