I'm a local and gonna stick with all Miami teams for life, even the Marlins. However, there are many Out of Town fans who have stuck with the Phins through many years of disappointment, when It would be so easy to change to a different team.
Why?
Changing teams has never even crossed my mind. Sure it'd be nice to like the Redskins even though they haven't done anything in 20 years. At least I could wallow in my sorrow with most of my friends who like them. The two Dolphins tattoos I have not withstanding, there's no chance I'd ever root for another team. If the Dolphins moved from Miami and became the Igloos of Arkansas or something then I might consider it but since that isn't happening, there's no shot of me jumping ship.
I'm loyal. They haven't won in 40 years. At this point it's all numb to me especially when I've seen 5 Spurs titles in 16 years. The Dolphins will never be able to top what the Spurs have done (for me too). But I'm loyal.
