Let’s say someone’s family was in the army, so they moved around a lot from birth, and they didn’t really have a ‘home,’ but they’re into sports—how do they choose their favorite team? Do they just decide to hold off until they move somewhere permanently, and then choose that city’s team as theirs?
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.
