At first I thought a young guns team and a rest of the world team was ridiculous, but a few seconds later I changed my mind.
Teams like Latvia and the like have absolutely no chance of winning. Next, aside from the most hardcore of hockey fans, who is going to want to watch games like Switzerland vs. Slovenia on a regular basis? Absolutely no one.
But...once you start loading up the 'rest of the world' team now suddenly Kopitar has some world class linemates and can have a legitimate chance to win some games playing real hockey. You can probably put together a roster from the rest of the world that can compete with the U.S. on a regular basis and might even be better than the Czechs. Now that's fun. Basically, the quality of the rosters for every game would be better than between any two NHL teams.
Whether or not you think its stupid to do this, you at least have to concede that the games would be far more interesting for casual fans. Also, as someone with a lot of exposure to people from these 'rest of the world' countries, they would absolutely get behind this team. As for the young guns, why the hell not. Seeing a team of U23 stars, whatever the protocol, is way better than watching Switzerland trap for 60 minutes hoping they can somehow get a 1-0 upset win.
If the goal of this tournament is to be traditional and nationalistic, this is a dumb idea. If the point is to put forward the most fun and best quality hockey, this idea is on point.
