for the same reason someone would like the cowboys, lakers, bulls, mets, etc. They cant stand that the bay area teams arent consistently the best, so they just choose random teams to like, or come up with a random excuse ('my uncle liked them in the '90s'). so in other words ur uncle was a bandwagon fan, just like u were. Theres not a team i like that doesnt have to do with me being from there, or family being from there.
