Rizzo doesn't understand you need some solid Triple AAA pitchers to have to draw from the deck in order to have a solid foundation. Peacock and Milone were both solid players to call up on in case of injuries to the rotation or inning limits. Now all we have is AAAA garbage.
Right now, Gorzelanny, Stammen, and Maya would be the first three. Solis, Rosenbaum, and maybe Demny should be ready by the end of this year. Purke, Meyer, and possibly Ray could be ready by mid-end 2013. The depth is hurt for now, but that is a small price to pay to have a dominant top 3.
Also, there are six starters right now, so one of Lannan or Detwiler could be the long man or be traded for depth.
