Something people need to look at is not what he put up for numbers, but how he did it.
I got to see every game. He was consistent and rarely looked out of place. Maybe a couple times when a guy got up on him, but that was usually when a team mate took way too long to help him out. And during the regular season were fouls do matter (unless your Miami, sorry had to sick that in) players wont D up as much like that and be over aggressive. I also think he'll learn the PP move of sweeping under the defenders arms creating contact for the foul which will get rid of a lot of that too.
His offense came from every were's on the court. His 3 needs more work, but its there. 20 feet and in hes money though. I can see him and Rondo working teams like they did with KG and the pick and pops. KO is perfect for that, because if a play plays tight he can still take it to the hoop or pass.
Passing was major. I really hope now with young legs they run a motion offense. KO,Rondo and Green will rack the assists up. If they get a decent C, KO will make him look like a boarder line allstar. I mean look at Melo a couple times that KO passed to him and the position he was in to score.
His defense wasn't as bad as people say. He rarely got his ankles broken or blown by. He didn't block a lot of shots, but made guys take tough shots. He held his ground on one possession were some one was pounding it in the paint dropping his shoulder. KO barely moved and got called for a foul. It was crap, should have been no call or offensive. I think a couple more months and you'll see KO take a couple bumps and then go down with good contact to "sell" the foul. But I don't know if thats part of his game to sell fouls, be might just be hard nosed.
Needs to work on the body, but can over the summer pretty easily. His Base is good, just need to define.
I know the rookie class is weak, but if he even gets to the top 3 rookies at the end of the year that's impressive no matter what the class is.
