Well I'll have to disagree. The NBA is full of men. LARGE men in that paint and basketball is more physical than a lot of people give it credit for.
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.
