I don't think Russian posters care so much about the result as they do the lack of effort in Game 3. You always want your team to show up and make a good account for themselves. Obviously, jet lag is a real human physiological condition, but it shouldn't be used as an excuse for a poor performance. After all, Russia accepted the conditions for the tournament in advance, so why complain now?
In fact, Russia receives a real tangible benefit(s) for this tournament, which is why they are interested in continuing it. For Canada, I think the main benefit is that allows CHL teams to effectively recruit Russian players, which they seem to continue to want to do. Without the series, Russian CHL'ers would be effectively cut out of international competition, and removed from the view of KHL teams, should their dreams of glory in the NHL not pan out!
