I was a proponent of a legit world cup (last one didn't count, imo). But, only if it is going to be a regular tourney. Whether it is every 4 years, every 3 years, whatever. I don't want it to be something where every now and then they hold it and the format is something whacky.
I am starting to think that if we are ever going to have a best-on-best International tourney and the NHL is not going to shut down for the Olympics, then it is going to have to be the IIHF that gets the ball rolling. It is not going to be the World Championships. I know it is popular in Europe, but you can't have a legit best on best tourney when players are still playing in the play-offs. It would have to be 3 years of the World Championship when it currently is played and the 4th year move it to early September as the World Cup. We can argue about it until we are blue in the face, but the NHL is not changing their calendar to suit the IIHF's World Championship and it doesn't seem as if they are interested in shutting down for the Olympics. The arguments for and against shutting down for the Olympics have been beaten to death on here, so no real need to bring it up again.
Bottom line, if you are reading this forum, you likely want a best-on-best international tourney. To get that, I think it is going to have to be the IIHF that takes the wheel here.
