Great points, Waukee Blues!
For more perspective look at the Sharks. They are about to have one of the worst collapses in HISTORY by possibly losing 4 straight to the Kings! Their history of playoff ineptitude is even worse than the Blues. I don't even think they've been to a conference final and if they have they haven't won!
I believe the Sharks are cursed because their team doesn't belong in San Jose, it belongs in Oakland where the Seals came from. That's how the Gund family got the franchise. At least with the Seals, by merging with Minnesota and moving to Dallas, they have a Stanley Cup in their story.
The worst collapse imho is the city of Atlanta. They get the Flames, they get moved to Calgary, win the Cup. They got the Thrashers and they moved them out to Winnipeg. If they win the Cup in the near or even distant future, that would make Atlanta THE cursed NHL -anything-, period. Even Quebec isn't as bad off.
