Under Kivi, Armia played a pivotal role in helping his hometown team claim the Finnish Elite League title in 2013.
His three goals and eight points in 16 postseason games were huge, of course, but Kivi remembers one regular-season marker in particular that made all the difference in the world.
"He was a first-line winger, and he scored the most important goal that season. We had a really, really hard time that year, going up and down. It was the most important game. I think it was in January. He scored in overtime against KalPa, and after that we won 15 of the last 16 games," said Kivi. "That's the goal I will remember all my life. Everything changed after that goal. Everything changed."
Kivi has been tracking Armia's progress in recent seasons, and he has thoroughly enjoyed watching his game steadily improve between Winnipeg and Montreal.
His ex-pupil's penchant for being reliable at both ends of the rink is especially gratifying for him.
"I knew when he left for the NHL that it was going to take a few years to adjust. When he was 17, he was only focusing on offense, but he's really good defensively now. He has a good eye for the game," praised Kivi. "He's even killing penalties, so it's nice to see how he's grown."
