I love the thinking of "Well if you strip away his great draft picks and all the games he has won, he really ain't shit!"

Basically you can fry him for the Harden trade, though personally I think there were various factors at play there. It shouldn't fall squarely on him but sure, he is the GM, so he has to accept that it does.

Beyond that he has drafted well and managed assets well. He made the most of the Jackson situation and killed it here. They have drafted Durant, Westbrook, Ibaka, Jackson and Adams. The Waiters trade kinda sucked but he took what he could get to fill a need. I don't see how anyone could see Presti as anything less than above average. Have you seen some of the stiffs employed as NBA GMs?
