Growing the game.......oh sweet potato. Sorry you won't be able to put skates on your children's feet, Spain parents, because you haven't been able to see the best NHL players at the olympics! Oh wait.
Please explain what difference would it make, in growing the game, if there was SVK and SWI or whoever, instead of Team NA and Team Europe. Do you mean growing the game among casual fans, non-hockey countries, or among teams themselves?
Because I don't think we should invite Korea to World Cup just to promote the hockey there, and neither I think Norway or Slovakia will see a fall of interest in hockey because their countries were not invited here. If you mean growing the game among actual teams, how does Slovakia losing 1-7 to the States help them to get better? Actually I think the IIHF Whc is good enough for growing the game. You see how much of a progress teams like France or Norway made in the past ten years. All that without playing the star-loaded teams.
