No team I am a fan of in any sport has won a championship in my lifetime. I'm due.
So you either don't like baseball or your Philly loyalties don't extend to other sports.
If I only stuck with Pacific Northwest teams I could say the same but for baseball my team is the Toronto Blue Jays who did win back-to-back World Series in the early 90's. And that was quite a thrill. It really is super awesome when your team wins.
And the BC Lions have also won 4 Grey Cups in my lifetime but that's CFL. That's like MLS level and only a step above arena football and the WNBA.
Team Canada winning Olympic Gold Medals in hockey in 2002 and 2010 were both really exciting though. Both had something special to them to with 2002 being the first gold in 50 years and 2010 being in Vancouver. I don't know if the US winning Gold medals has the same effect for Americans. Canada is like a rinky-dink country in the grand scheme of things so Olympic Gold is a big deal to us.
Watching the Mighty Ducks win was pretty annoying. 2004-07 fucking sucked as Tampa Bay, Carolina and Anaheim all won. Each was like barely ten years old (if you discount Carolina's time as the Hartford Whalers, which makes sense since it would have been a different fanbase) in non-traditional hockey markets where I question how many dedicated fans actually care about them.
Carolina's is the worst because those idiots had missed the playoffs the previous two seasons and then would miss them again for the next two. They are the very definition of a fluke team. And the worst thing is that every three or years or so that they do make the playoffs they always go deep making it to at least the conference finals. They're the Florida Marlins of hockey, being completely irrelevant for years and years only to periodically pop up and break the hearts of another team's fans.
