The most interesting thing about that survey was the backlash against Lebron James. He didn't get a single vote in any of the defensive categories other than "defending the passing lanes", despite being All-Defense last year. He got almost no support for MVP, despite winning by overwhelming margins the past two years, and 29% of GMs said Durant is a better SF, period. The Lakers, rather than the Heat, were seen as the favorite in the East, and 26% of GMs don't think they'll win their division.
It shows that GMs are people, too, and are prone to the same biases and dislikes.
