it looks like a consensus is building in favor of Kelly. If it is this close then you have to go with the 7 footer that does not have a history of weight and lumbar spine issues. If KO had McHale length arms we would not even be having this discussion, then again if he did he probably would not have the handles he has right now. Who knows.
I would vote to keep KO if it came down to a vote.
If he did have McHale length arms there's probably no way he lasted to #13 for us to take. I think KO looks like he will be a very effective scorer. Yes, he is on a bit of a hot streak. But he has performed at this level before, ie post-allstar break last season and at the collegiate level. The shooting ability is not a fluke.
The question is how will KO adjust when defenses start focusing on him, throwing double teams at him, when they realize he is taking on a bigger role in our offene. If he can still shoot well when teams focus on him as a top 2 scoring option, well we then we've really struck gold.
I am very high on KO's chances to become a top scoring option for us. 7 footers who can handle, pass, and score don't grow on trees. That's a pretty unique offensive piece. And when he makes the opposing big come out of the paint to guard him, that just opens things up for the rest of our offense as well.
