actually, having dealt with yankees players on a more personal level than most fans, i can safely say the majority of them are actually really nice, classy guys. The team does a lot to promote it's image; players always show up to the ballpark in, and leave in nice suits, will almost always stop for a young fan, and are nice guys to deal with at work.
most top teams are like that, but the yankees really go the distance every time.
