I love the Cup idea too, but it can never happen as long as the KHL and NHL are the two biggest leagues. The KHL wants nothing other than superiority and will do anything to get it. The NHL won't do anything to risk giving the KHL such status. On top of that, the KHL is completely corrupt. Soccer has had to deal with its own cup issues, and the match fixing that has been caused by countries that are less stringent about controls have been damaged as a result. If a different country were #2, I'd be all about it. Since it's Russia, I can't be.
And, again: I don't care about losing a bronze-medal game in hockey. Once they lost against an obviously-better team, that pretty much ended my rooting interest. But every media report on the team has been "what a bunch of overpaid whiny losers", and Joe Six-Pack in the upper deck might buy that explanation.
I like the Olympics a lot, and even follow their work during the off-season. I have thought for a long time that the USOC is an old-boys network that is pretty much interested in PR and not interested in developing athletes, and their lack of effort is starting to come to a head. I don't blame them for hockey, because that's 100% the NHL. But I do think the USOC has needed a big overhaul for years now, and I'm hoping that this does it.
Any evidence of KHL's complete corruption? And what does soccer have to do with KHL? Also, if there was enough money (i.e., fan interest) in it for NHL, I am sure the league would do it in a heartbeat. The issue is that it's hard to predict fan turnout for a KHL/NHL match in US. In Russia, people will likely pack the stands to see NHL stars play, so that's a non-issue.
