Sweden versus Russia, 3 p.m. ET (ESPN)
The precise offensive juggernaut of Team Sweden will attempt to use its lineup depth to exploit a weak Russian defense. Sweden is one of the better puck possession teams in the World Cup of Hockey, and it needs to dominate in that area in order to have success. It starts with faceoffs, and that was one of the primary concerns during training camp. The one positive aspect of an embarrassing loss to Team Europe in Sweden's final preseason game was the Swedes' success in the faceoff dot.
Controlling the puck immediately will be a key factor for Sweden. When the Swedes don't have the puck, goalie Henrik Lundqvist needs to be at his best. He struggled in the first round of the playoffs for the New York Rangers last spring and wasn't sharp in the two World Cup exhibition games. He has shown in the past that he can play well on the big stage, especially at the international level. Russia is a top-heavy team with many offensive weapons, including Alex Ovechkin, Evgeni Malkin and Vladimir Tarasenko. In order for Russia to win, it will need to score a lot of goals because its defense is suspect. Sweden needs to force Russia to make mistakes
Line watch: Team Sweden possesses one of more cerebral lines, not only for the World Cup, but also in the NHL, with Daniel Sedin, Henrik Sedin and Loui Eriksson. Sweden's top line also comprises part of the team's first power-play unit. Those three forwards, along with two-way defenseman Erik Karlsson and fellow blueliner Oliver Ekman-Larsson, form a dangerous combination, so opponents need to remain disciplined. Eriksson may not look strong, but he can play a heavy game in front of the net. There isn't just one dangerous line for Russia. Ovechkin, Malkin, Nikita Kucherov, Tarasenko, Evgeny Kuznetsov, Pavel Datsyuk and Artemi Panarin all have the ability to score goals. -- Joe McDonald
Team North America versus Finland, 8 p.m. ET (ESPN2)
As they wound down their final practice of an extended training camp on Saturday, you could tell the kids had just about enough of the preparation. They're ready to play in something that counts.
On Sunday, the youngest team in the World Cup tournament will get its chance, and it's a fascinating matchup with an opponent in Team Finland that is the opposite in many ways to Team North America.
In Finland, you have a team with a distinct style of play. The Finns defend exceptionally well, play as a five-man unit with a nice mix of skill and sandpaper. You know what you're getting in the Finns, and they tend to do better than outsiders anticipate in these tournament.
Team North America? Nobody is quite sure what to expect. The team is loaded with speed and skill, but it's questionable whether it will defend enough to win tight games and whether the young guns will respond to physical play. It makes this game fascinating.
It's also a high-profile showcase for two of the newest stars entering the NHL this season, with No. 1 overall (Toronto Maple Leafs) pick Auston Matthews squaring away against No. 2 overall (Winnipeg Jets) pick Patrik Laine.
Laine has impressed his counterparts in this tournament with a shot that has been compared to greats from Brett Hull to Alex Ovechkin. He has the potential to be the breakout star of this tournament.
Line watch: The line to watch in this game is the newly assembled top line for Team North America, featuring Connor McDavid at center with Auston Matthews and Mark Scheifele on the wings. Team North America coach Todd McLellan constantly shuffled his lines throughout the exhibition season, looking to get his top guys going. McDavid went three games without a single point during the prelims, but this line could be dangerous, with Matthews and Scheifele giving Matthews linemates with size, strength and the necessary hockey sense to play effectively with McDavid. Matthews has slowly worked his way up the Team North America depth chart, and the team's youngest player hasn't looked out of place even for a moment. -- Craig Custance
