No, the Blues are not the Cubs of hockey, because there are many hockey teams that struggle to have a successful record. With the Cubs, they are the team that everyone secretly supports, even if they are not a fan. The Blues are not as endearing to hockey fans who also support other teams.
The Cubs were a strong athletic organization a century ago and have even won a few rings. However, the Blues have not been so lucky in their organization's history. Even though both teams have had a tough go over the past few years, the Cubs can look back to old historical wins, where the Blues can not.
