Re: How did LeBron manage to finish 2nd in DPOY voting...
Lebron isn't a center. He is a forward and he defends the forward position at an all time great level, when you factor in every facet of defence.
You can argue that there are a few centers that effect games around the basket defensively, and this can have a bigger impact than a perimeter defender.
However I would say Lebron's ability to both defend the perimeter and the rim from a swing man position puts him as a top 3-5 defender in the NBA.
Keep in mind every defensive lapse of his is magnified, and he plays in a complex rotating defensive system that is based around his abilities, with other players with similar versatility but less ability being asked to play within it also.
