Kendrick Perkins used to be a more-than-servicable NBA center. We're not sure what happened to that guy. Because the Kendrick Perkins who played in the 2013 NBA Playoffs was one of the worst players of all time. In fact, from a purely statistical basis, he was the worst player in playoff history - recording a negative PER in 200-plus minutes. (Advanced stats are a wonderful thing until they point out that you're worse than anyone ever.) Anyway, Perk is under contract for two more seasons, and while the Thunder can legally amnesty (if not euthanize) him this offseason, his presence is representative of a bigger front office issue. (Hey, whatever happened to James Harden anyway?)
