I was reading an article by Maury Brown detailing the difficulties of relocation and expansion in baseball. Interesting read in its own right, but it got me thinking: hypothetically, let's say that somehow, MLB managed to convince the Mets and Yanks to allow a third team in our area. For the sake of this, let's assume that the team was placed in either Northern NJ (say, Newark/Harrison), or Western CT (Stamford/Danbury), or Brooklyn, NY, whichever one is most local for you. Would you switch allegiances to the new team? I suppose this would not apply to people who live in Queens, or in Manhattan, or outside of the NYC metro area (but you can pretend you live somewhere else if you like). This is just a curiosity for me; I wonder about diehards switching sides, and building new fanbases from scratch in this era of sports.</a
