I saw a lot of post-game press conferences, and never heard Girardi knock any of his players. In fact, he seemed to go out of his way not to do so, in spite of reporters goading him to do so.
Cashman should be out of there. If it weren't for the crazy high priced, long term contracts he offered - Sabathia, A-Rod, Ellsbury, Chapman, maybe Teixeira, come to mind off the top of my head - the Yankees wouldn't be in a "rebuilding" phase.
