Hockey maybe canada's National sport but 4 of the original six were US cities! Detroit, Chicago, NYRangers, Boston, with toronto and montreal being the only 2 canadien teams!
*the city of Detroit, a river between Detroit and Windsor,Ontairio the river is maybe an 1/8 of mile wide between the 2 countries for those that don't know*
So not taking any credit away from canada or your passion, but I as a life long Detroit resident that can cross into canada in 15 quick minutes from my front door and I have loved hockey just as and every bit as much as any canadien has since I discovered hockey when I was a child!
Canada despite it being the national sport is poorly sponsored or should I say supported in canada! Quebec, Winnipeg, and Ottawa lost their NHL franchise's / teams, I feel the US market has both helped and hurt the NHL!!
the NHL has flourished in the USA despite poor choices of where to allow expansion teams too take root!!
I think where the US influence has hurt the NHL is because of the cities that have a poor fanbase / attendance and for the most part up until the salary cap / market sharing (which is absolute

IMO) its the only reason the newer expansion teams still exist!
I liked hockey when it was the NASTY HOCKEY LEAGUE, the real NHL per say, not this NO HIT LEAGUE or these insitagator rules and all the pansy penalties that are drowning the game as tradition meant the game too really be played!! die hards remember, cherish, and pray that NHL comes back sooner rather then later!!
We definitely have a watered down NHL thanx too SCARY BETTMAN trying too shove the watered down PC friendly version of the NHL, which was otherwise a very violent exciting game up AMERICANS ASSES by introducing hockey too cities its never really been too popular!!
