He's made a bunch of terrible big $ signings over the past years - A-Rod, Sabathia, Ellsbury, Chapman, A.J. Burnett, and others which haven't been as bad, but weren't all that good Texeira, Damon, McCann, Pavano, Giambi, to name a handful - which helped to turn the Yankees into a crippled old team which had to be rebuilt. I won't even bring up Andrew Miller.
All of a sudden, the Yankees have some good young players on their roster, and Cashman is a genius. Girardi's out - either he obviously had nothing to do with holding a mediocre team together over the past seasons, or Cashman wants all of the credit for any current success and doesn't want to share it. I don't buy the idea that Girardi couldn't relate to the younger players. I'm sure a lot of that comes back to the fact that he benched Sanchez for a few games after h\is defense was terrible, or the fact that he started Romine for one game of the postseason. Now Cashman's hired a guy who will probably cater to his wishes with no questions asked.
I don't hate Cashman. I just think that he's a terrible GM who's had a lot of money at his disposal and little success to show for it. And for those who bring up the Yankees "dynasty years" of the mid-90s to early 2000s, Gene Michael was the architect of those teams.
Just my opinion, which counts for nothing in the real world. Cashman won't be fired.
