"I was happy with (his first season)," said Chiarelli. "I've seen young 18-year-olds play in the AHL, I've seen some outperform him and most not.
"Every time he touches the puck in the American League it pretty much turns into a scoring chance."
Following the conclusion of the AHL regular season, Puljujarvi was loaned to the Finnish national team for the 2017 IIHF World Championship. Finland fell short to Russia in the bronze-medal game.
Overall, the season was a learning experience for the first-year Finn. Navigating the ups and downs left him frustrated according to Chiarelli. It's something he had to fight through and will continue to grow from moving forward.
"He's a young kid from Northern Finland and when I talk to him he's frustrated he wasn't scoring," said the GM. "I told him you just worry about your wall work and work behind the red line, the defensive side of the red line, and don't worry about the offence. I have no issues with the offence. I think he has a little trouble not accepting, he's a very understanding kid, just knowing he has that period of apprenticeship that maybe he didn't think he was going to have. But he's a good kid."
Puljujarvi said one of the biggest adjustments to make was the speed of the game on the smaller ice, but the language barrier was the hardest.
"It was tough," Puljujarvi said. "Sometimes, I'd play good, but it was tough with the new culture."
Puljujarvi added his goal is to come into next season with more confidence. As the top prospect in the system now, the Oilers hope he builds off lessons learned in year one as he prepares to hit the ground running in year two.
