I have played my share of hockey against tired overseas players so I know what new surroundings and jetlag will do. There is huge difference between rested, used for rink size and timezones players and people who aren't. Have seen how NHL player(back then junior tho) wasn't anything special when being tired and not used for surroundings. And then dominating when being used. Maybe you should travel as well and you would see it as well if you haven't.
I have. I played my share of hockey. Furthest away travel was to California, we played in Oakland early the day after we landed in San Francisco from Toronto. Of course, it was nowhere near this level of play, but I am familiar with travel and jet lag.
I understand your point of view, but IMO, the travel and other factors you have suggested are not as significant as you think they are. And its not like Canada doesnt travel for similar tournaments and face the same kind of situation. Maybe the best comparison is the Ivan Hlinka U18, I doubt the CDN players have much too much big ice experience at that point, they have the jet lag too since its in Czech Rep. & Slovakia every year. And Canada has done quite well in this tourney, and I dont think they go into it with the mindset that they are at some extreme disadvantage.
Another one of your reasons was teams not bringing top players. Considering the fact that Canada sends 5 regional/provincial teams, not 1 team. You also mentioned Ontarios population, but Team West also finished ahead of the European teams, and Manitoba and Saskatchewan have a population of less than 2.2 million.
Lastly, I honestly think for the most part, you have confused CDN fans giving props to team Ontario, as bashing the other teams. I think I've been in all the U17 threads, and other than a post or 2, which arent even that bad, I really dont see much to complain about.
