There's a lot to like about him, and a lot not to like. Specifically, his TRex arms, his smallish frame, and his lack of an outside shot. But with his instincts and athleticism, he'll probably fall in the draft and be good value for whoever takes him. You can't teach his vertical and what a freak athlete he is.
I have a suspicion he'll jump right out of the gate as a legit rotation player who'll be rookie of the year candidate. But if were a GM, my concerns about short arms might override my belief in his potential. Kind of hoping he gets taken before us and pushes PJ Washington down to us.
