It's interesting. As fans if makes us wonder what exactly we are fans of. Its surely not the ownership. Neither is it completely the players because they come from all over and come and go, understandably seeking the best contracts.
That said, I grew up and am still four hours away from the games but only being able to get up a couple times each year just made the experiences more special. Would it change if they moved to be five hours south of me? I don't know. In a sense it would seem they would effectively become a different team, even if they kept the name. I guess I would remain a fan, if for no other reason that there would be no Chicago alternative outside of the Cubs. Its all hypothetical though anyway...right????
