Simple. You feel out which team you associate with the most.

I lived in Vermont. It has no MLB, NHL, NBA or NFL teams (I really can’t see anyways how it’d have either). So, naturally, it’s New England and you have a plethora of teams to root for. I naturally gravitated to the Boston Red Sox. To me, they were the underdogs, lovable idiots who really try hard to make it and I’ll never forget the year of 2004.
