I agree, this isn't Cashman's fault, he acquired the talent. The Yankees have talent, no doubt, possibly more than the Red Sox, but they don't have a team. They have 25 individuals, and that is an organizational failure that goes right to the top. Hank or Hal... whichever bonehead thinks its a great idea to spend obscene amounts of money can be blamed here.
Personally, as a Sox fan, I love it. The Yankees can't win no matter how much talent they acquire. This further proves that heart matters more than talent, and you can't buy heart.
