I have a specific reason for excluding the Canucks.
Every team - including all of the non-Canadian ones have aspects to like and dislike. These things evolve over time. I generally don't give them much thought in regard to this issue.
It is full on tribal with me. I'm a Jets fan because I'm a Manitoban/Winnipeger. If the Jets are out I cheer for any Canadian team because I'm Canadian. Frankly, I can't understand any other attitude. If not for the tribalism you might just as well figure out which team is the best and adopt them as 'your' team. Not that you will have any affiliation with them because your loyalty will move to whichever team becomes better.
But that is just me. People are free to make their own choices for their own reasons. Some of them will baffle me though.
