We saw real teams like Canada, USA, Russia, Sweden, Finland and Czech face off, and two special teams called Team North America, comprised of the young and upcoming stars, and Team Europe, a mish-mash of players from other countries. It was highly entertaining hockey.
The NHL has more influence over buildings by hosting the World Cup in North American . Also insurance that the NHL and IOC battle on constantly, will not be a problem if all NHL teams are involved as well.
They NHL will also have the ability to influence important decisions that affect the players competing in the competition, as they can select Russia if they like, or perhaps make another U23 team as the first was highly successful.
