With Sunday's games in Sochi, the group round of the men's Olympic hockey tournament came to a close. From now on, every single game will be an elimination contest, with the winner advancing to take on an even more difficult foe and the loser being struck from the tournament.
We know now where each of the tournament's 12 teams will be seeded, but our knowledge is dwarfed by our ignorance. This year's games have already featured numerous surprises—from the surprisingly potent Slovenian team to Russia's failure to make the quarterfinals to the implosion of Slovakia—and if history is any guide, more are on the way.
What, then, are the most pressing questions as we head into the elimination round? That's what the following slideshow will answer.
