KO is better than a capable defender. His defensive rating was good all year long
when he is on the floor, the "team offense" looks stressed. Just because of his size, instincts , mobility
Now you give it to an Anthony Davis move out of the way , KO will have issues containing him 1 on 1
So as of now, very good team defender and needs to take his conditioning to the next step to be an adequate 1 on 1 defender against top players
