Unfair to criticize Perk's defense. He is a very good defender. Dude is still recovering from knee surgery and sprain in other knee. KG often looked bad last year on D, why? Because he was not fully healed and conditioned. I favored the Perk trade from the get go, but give our Perk some slack. He will be awesome for the OKC especially next year, when they dethrone the Lakers in the West. Still a year away.
