I live a few minutes away from UK's campus. I've seen Skal (and Murray and Ulis) play a few times. Skal's movement is insanely smooth. So hyper athletic. Really great shooter too. I look at Skal as a Small Forward trapped in a scrawny Center's body. If he develops his body further, and learns how to play closer to the hoop, he's an all-star waiting to happen.
I'll take Skal at 13 all day. He's a 20 year old with a crazy high ceiling, and I'm not super in love with anyone else around that range. His draft situation reminds me a lot of Miles Turner last year, but with mentality questions opposed to health ones.
