Well if you are going to go with a NY team, it is better then the other two options ( I am assuming you are talking football and NY Giants as opposed to the baseball Giants in San Fran) However, although they are the best choice for a NY football, I never fully understand how a team that plays in NJ is a NY team.
It's the American way!

Yeah, the giants in football. I took great liberty in enjoying the patriots takedown.
I'm not a west coast fan, although in football, my number 2 team are the 49ers.
