Joks knees are clearly getting better and better. When he arrived at iowa it seemed like he could barely get up to dunk but the Rutgers game he showed nice hops and was dunking with ease. This could also be a reason his defense has been better also, it's obvious he feels more comfortable than ever with the knees. Fran made another great decision sticking with this kid, he's a big big reason the hawks are #3 in the nation.
