Anyone would struggle with Durant, but give him 20 more lbs with that length and players like Ibaka would struggle with him, even as a rookie.
I also disagree that he's not playing hard. There is just not much you can do when players can just move you out of the way with their muscle. I feel his pain. All the basketball smarts in the world can't help you in that situation. Unless you just get p****d and start fouling.
