The Olympics are the peak. With the recent fight between the NHL and the IOC, the NHL tried forming its own
Hockey World Cup based on another try a decade ago with... not great results.
Some NHL players planned to ignore the NHL ban and go to the Olympics anyways (especially the Russians), but then the IOC also banned NHL players from participating. The current ice hockey Olympics for men are with people who are retired or in other leagues (like the SHL and KHL). The actual best of the best are banned.
