I guess thats the key difference in New York and Boston fans.
Not really. I don't mind Patriots hate, and I certainly enjoy hating the Yankees. I want them to fail, and I look forward to the whiny headlines blaming A-Rod for the whole thing. I'm looking forward to some smug superiority after the Yanks miss the postseason.
There's a big difference between wanting A-Rod to fail miserably for the rest of his career, being forever branded a loser and choke artist, and wanting him to seriously hurt himself. Injuries are a reality of sports, and I don't feel too bad when they happen to the other guys, but I don't wish for it or gloat about it. It's classless.
Think I'd be cheering like that if Eli Manning went down, or Favre? Get real.
EDIT:
Everyone hates New York and Boston. We just don't vocalize it because we hear enough about their stupid rivalry anyway.
Cry more, bitch.
