The 17-year-old center and native of Kotka, Finland, is No. 6 in NHL Central Scouting's midterm ranking of international skaters. He has spent most of this season playing for Karpat in Liiga, Finland's top professional league, where has 11 points (five goals, six assists) in 33 games.
At that age, playing against men is difficult, but the experience has proven valuable.

"I didn't get too much ice time (in Liiga), so it was a little bit smaller role," Kupari said during the IIHF World Junior Championship in January. "But they're tight games and pretty big guys, so it's hard to play there. It's important to get ice time so sometimes I play with juniors or in the second-highest league in Finland."
Competing against veterans also gave Kupari the opportunity to work to his strengths and find other ways of managing the game when his size (6-foot-1, 183 pounds) may not help him.
"They're stronger than me so I have to be bigger inside the goal or something like that," Kupari said. "It's a good challenge for me every game. I'm a fast skater so I can challenge big guys with my skating."
