For what it's worth, I think a lot of players say that because it's seemingly the right thing to say to the media, as opposed to saying "hell yeah it's about the money, this team better pay up or I'm telling you *******s to shove it" they say something polished and politically correct like "I definitely want to be here, it's not about the money" or if you're a free agent just signed by the Yankees "I've wanted to be a Yankee ever since I was a little kid"
