The World Cup of Hockey will begin Saturday, reviving a tournament that has been dormant since 2004 with a slightly altered format. Aside from the format, not much has really changed. Canada won that tournament in 2004 and come into the 2016 event as the heavy favorite.
The thing about short tournaments like these is that anything can happen, but as Canada has shown in the last two Olympics, when they're on their game, they're almost impossible to beat. That being said, the margin for error in this tournament is incredibly slim. One misstep in the preliminary round could cost a team their spot in the semis and once it gets to that point, the game could come down to a bounce here or there.
