"The biggest thing with Harry is how much respect we have here because he competes so hard," head coach John Tortorella said during the postseason. "As you go through a game and there's some struggles, it doesn't bother him, he gets ready for his next shift. He makes up for a lot of things, a lot of attributes that he doesn't have like a (Seth) Jones, he makes up with a willingness and a competitiveness.
"That's a pretty good story for us as far as where Harry was sitting out and watching all the time to being in the second round and playing some good minutes for us."
Harrington said he became more and more confident as the season went on, which helped him settle into his game. A former member of Team Canada's World Junior squads and a standout with OHL London, which helped make him a second-round pick of Pittsburgh in the 2011 draft, Harrington played in just 25 games his first two NHL seasons with the Penguins and Toronto before being acquired by the Blue Jackets for Kerby Rychel in the summer of 2016.
"At the beginning (of the year) I wasn't really playing, then I got into the lineup and got to stay in the lineup and that was great," he said. "You start trying to assert yourself and show the coaches what you can do and play the game that you know you can play and the game that's kind of brought you to that point. That's what I tried to do, and I know I still have a lot of room to grow.
"I still want to get to the game I know I can get to, to the level I know I can play at. It's almost a thing where for me almost every game or every 10 games I got more confident, and so that's all I'm trying to do is keep working on the areas of my game I need to improve this summer and have the same mentality when I come to training camp."
Looking back at the road he traveled to ink this deal, Harrington said, "It feels good when management makes a three-year commitment to you. I've had a lot of help the last three years. There have been some frustrating times, that's for sure, but I've had a lot of help from the guys on the team and the coaching staff and strength coaches. They've stayed with me and I kept working hard, and I guess in a way it feels like it paid off today so it's a nice feeling for sure."
