Personally I don't know who gets my voice more ragged yelling and cursing at them on game day, Butler or Castagna? Castagna cost us against GWS last year, Butler will do the same if he is not careful. Both need to improve and I think Butler has a better chance because it would be tough for Castagna to do anything about his lousy skills at his age. Still, unlike Rioli, neither of them are untouchable come trade time. Butler just has to stop showboating!!!
