Yankees Suck?

As the Mets were winning a nice crisp game, the crowd became obsessed with the Yankees. There were several “Yankees Suck” chants. Why? Why are you concerned about them?
Is it the way they import stars from other teams? is it their better record? Is it that they are getting a new stadium? Is it that they couldn’t win their division last year? Is it that they have a former Yankee managing them?
I’m not sure what qualifies as sucking but they are the only team to win a World Series at Shea in 20 years. Learn from Boston. The Yankees own the past, there is nothing you can do. Win some championships and things change. Anyone who was around in the mid 80’s knows how fast the front-runners will come to Flushing.
