Some Guy At Work went to a Phillies game last year. He was at a bar in Philly talking to his friend about how much he hates Buck/McCarver. Another gent in the establishment overheard the conversation and said, Hey, I used to work with them. The guy went on to say that the reason for the unceasing Yankees fellatio is a sponsorship thing and that to malign New York would anger the sponsors. And that would be bad.
I know that whenever you hear someone tell a story and it begins with "I heard it from..." your bullshit detector automatically goes on. So is this a credible person in my opinion? Yes. And this story is not totally far-fetched. There you go.
