The high point of Puljujarvi's season was World Juniors, where he topped the scoring race with five goals and 17 points in seven games. The Finnish coaching staff chose not to name him to the World Championship roster.
Aho earned his spot thanks to a regular season as the leading scorer with Karpat of the Finnish Liiga, scoring 20 goals and 45 points in 45 games. Laine was named postseason MVP of the Liiga Playoffs, scoring 10 goals and 15 points in 18 games when he helped Tappara to a championship.
"It was exciting to see them win because they lost in the finals three years in a row," Barkov said of his hometown team.
"We have those two talented guys there, they have been showing that they can play at this level," Jalonen said of Laine and Aho. "When you build a team, it's good when you have talented young kids like we have, they always give a positive energy. I'm really proud of those two guys and how they're playing. They're a big part of our whole team."
Another young Finn who played well against Hungary was 21-year-old goaltender Juuse Saros. Finland's gold medal-winning goalie from the 2014 World Junior Championship who was taken by the Nashville Predators in the fourth round (No. 99) of the 2012 draft. Saros stopped all 13 shots he faced Wednesday in his first start of the 2016 World Championship tournament.
Meanwhile, forward Mikko Rantanen, another top prospect, waits in the wings. Chosen by the Colorado Avalanche with the 10th pick in the 2015 draft, Rantanen played nine games in Colorado before spending most of his first North American season with San Antonio of the American Hockey League, where he led the Rampage with 24 goals and 60 points.
Finland has two remaining roster spots available for additional forwards. Rantanen is with the team, and could be added for the late stages of the round robin and the medal round.
