In a wide variety of events in these games, announcers have commented on the significant number of Canadian (and American and Chinese) athletes in sports with very deep national team programs who are competing at these Olympics for other teams, including Australia, Germany, Great Britain, Russia, etc. All they did was move over to some of these other countries for a couple of years to train, with no apparent previous ties to these countries at all.
If it works in sports where the talent gap is far smaller than in women's hockey, it seems to me like a no-brainer. There must be literally dozens of NCAA players who would jump at the chance to live in Europe or Asia while in their 20's for a few years and continue to play hockey, not to mention get the chance to compete in an Olympic games.
The reverse kind of cross-pollination opportunity also exists. The CWHL in which the Olympic athletes play in non-Olympic years, is currently basically a beer league at the moment with a big shortage of quality players compared to the number of teams. With the growth in quality in younger age groups, it's competitiveness is now generally a step down from the top PWHL teams, despite having a few Olympians sprinkled in.
Yet the CWHL apparently continues to prohibit/limit the amount of foreign players--including even Americans!--on their rosters. This makes zero sense in terms of either attracting more fans (there currently basically aren't any), much less in growing the game in either Canada and abroad.
Why is the IIHF, in conjunction with Hockey Canada and USA Hockey not showing any leadership in developing the sport and fixing these glaring issues??
