Well if everybody agrees on Winner getting the same glory than from Olympics or last world cups then there's no reason to want to win it. I'm just being little sceptical..
When all has been said and done, there will be a trophy, and there will be a lucky player who gets to hoist said trophy over his head.
However, what will read on said trophy? Is it going to be the name of a
country? I'd say the odds are very good that yes, it will, but even the possibility that instead the plaque will read "Team Europe" or "Team Young Stars" is enough of an insult to the sport itself that seriously, no self-respecting hockey player, expert or fan can put much weight on it.
Hell, by definition, it's not even international competition. Because that means exactly what it says on the tin, a competition between various nations. This... thing... will include two teams that do not represent any nation in any capacity. And if it's not really an international competition, the value of winning it - at least when compared to the olympics or earlier World/Canada Cups - is going to be pretty much zero.
I've no doubt it will provide a few night's worth of entertainment to any hockey fan who bothers to tune in, grumblingly or not. But if somebody tries to pretend it's going to have any lasting worth, be something people still look back fondly even after years have passed... well, yeah, no.
