Agree or Disagree..Kendrick Perkins "skills" are decieving?

People were saying he wouldve made a difference in Boston..but REALLY?! What exactly has he done in OKC? Serge Ibaka has done TWICE as much..even Nick Collison has done more..he is either a pretender or maybe it's just first time jitters and he will adjust..but besides aggression(which hasnt done much against Dallas)..he hasnt brought much to the Thunder.
