Although the games appeared to be enjoyed by everyone in attendance, it now appears not everyone supported the action. That being NHL legend, Dominik Hasek, who stated that the NHL is banned from ever returning.
Before the two games for the Global Series, the Czech government took a stance that no Russian players would be allowed to play. However, the Sharks and Predators claimed that they'd refuse to play if not all their players were allowed entry. Ultimately the government agreed to allow the Russian players access, but they apparently won't be willing to do it again.
