I would put Matt Cain above both of them and Anibal Sanchez, Ervin Santana, and possibly even John Danks and Shaun Marcum above Greinke. ?!? Based on what? Wins? Greinke has had a very pedestrian 100 and 102 ERA+ over the last two years. Yes, his pre-2010 stats are very nice, but he's been a mediocre pitcher the last two years and that worries me. All the guys I listed have been better than Grienke over the last two years. I'm not sure I would take Marcum over him because of age, and Danks mediocre 2011 combined with his career K/9 make me leery. Wait so you are serious? I'm assuming you're questioning the validity of ERA+? If you are, I can understand why you would be critical of it especially in the case of Grienke's 2010 where he was playing with one of the worst defensive teams in the league. However, the Brewers were a top 10 defense last year. Also, Greinke's line drive percentage last year was 22.4%. I guess it's possible that he just had an off year, but his K/9 have always been all over the place. He's a bit inconsistent in that way, and personally I don't think adding him to a high pressure situation in Chicago is going to be a positive influence on him given his social anxiety disorder. It's just a personal opinion though. I can see why you would be very interested in his consistently low BB/9. The guy is obviously going to be a huge committment and I personally would rather make the huge committment to Cain or Hamels. If not them, then a lesser committment to Sanchez or Santana. All things equal, of course I would take Greinke over everyone but Cain or Hamels. That inherent risk is not equal though.
