The focus should not even be on Durant or LBJ. No chance of stopping either of these guys. It's the Ibaka's and Martin's of the world as well as Wade and Bosh, etc. that should be the focus of the defense.
If Durant or LBJ can score 80 a night so be it. Shake their hands and congratulate them. But Ibaka can't go 11-11 or Martin get 25pts. That kills you.
