Sponsored by the NHL, the NHLPA, USA Hockey and Hockey Canada, the North American Youngsters will field the best U23 Americans and Canadians next summer in Toronto. I love the idea, but team chemestry coming off younger international rivalries and lacking a single national identity will be interesting to say the least.
Details will be hammered out amongst the four parties in July, and leadership is expected to go to dual citizens (you could certainly do worse than a Jon Cooper and Stan Bowman tandem).
Edit: Misread the original announcement h/t to wlubd. There will be an all-star team comprised of players of any age from countries not in the tournament. The NHL is on record saying this will likely be a one-time measure and there will be full qualifying tournaments in 2020.
