I also think there is some testicle shrinkage going on with OKC. Harden clearly is just not mentally in this series and Durant does not have the physicality to play with Lebron if they let them play rough, unlike how he was officiated in the SA series.
This morning I heard KD compared to Gervin because he is a fantastic scorer but isn't impacting the game in other areas. I think that is something he will have to work on. When he isn't scoring he's not really having much impact on the game.
But we really shouldn't complain too much. Bowen was rough with Lebron in the 07 finals (remember that uncalled foul at the end of regulation when Lebron went for a tying 3 point shot?). That's part of the game.
