Knox seems to have a very casual, even playful demeanor. He has loose body language. He's got natural tools for days, but he just has a casual gate, a somewhat loose handle and doesn't always look like he's playing hard. It will be interesting to see if and how he matures in a college setting. How well does he play with focus. He just turned 18. He looks like a kid.
Everything that people liked last year about DJ Wilson from Michigan--the size, length, shooting touch, ability to run the floor, ability to go out on the perimeter and disrupt shooters, the overall ability to play like a big wing, etc.--Knox has it all too. But Knox is 3 years younger than Wilson, is even more athletic, can attack more with the dribble, and doesn't appear to be the soft, non-defending, non-rebounding wuss that DJ Wilson is currently. Knox's ceiling isn't all that far behind Porter and Bagley, imo, but he's much more raw. In a draft that's deep with wing talent, Knox could be a value pick in the 10 - 15 range of the draft if he'll come out.
That said, it doesn't look like Knox has much of an in-between game. He can spot-up and attack close-outs. He can rebound and go. He can go hard at the rim. As a young guy he needs to refine every aspect of his game. I'll be interested to see if he gets featured as a scorer in UK's young line-up.
The question is whether Knox has it mentally and how he'll develop.
