NYY fanbase isn't much. There are those that are fantastic fans but then there are those fans that go to the games because its the thing to do.
If you've ever been to a Yankees home game (or a few as I have) you quickly learn that Yankee fans are really just loud and that's all. If we sent terp up to try and explain VORP to them they'd probably just throw stuff at him.
They really aren't a very bright bunch.
