As much as I dislike Pierce, one thing about the Knicks is that we always have "villains" against us. And he's embraced that role.
Dudes like MJ and Bron just love lighting it up at MSG and beating the Knicks. Then you have Miller and Pierce who just have something in them that hates the knicks. Wade is another dude that just doesn't like the Knicks (prob 2nd city syndrome.) For whatever reason, over the years teams have just always personally held something against, which is why we've had more rivalries than anyone.
I still hope pierce and kg have injury plagued seasons.
