"I knew where he was drafted, I knew where he came up. I obviously knew him just from watching games, but really getting to know him and watching him play on a night to night [basis], I don't even think Ryan's reached his full potential yet," Guerin said. "And I think what we saw this year when we moved him to center, there's a lot more there. I think we can help him become a better player and he's been a big contributor so far, but I do, I think there's more. I believe in him, I do."
Since his arrival in Minnesota nearly two years ago, Guerin has stressed "team," and that guys be willing to sacrifice individual accolades for the greater good.
While Hartman had to adapt his game to survive in the NHL, that realization encapsulates exactly the kind of attitude Guerin is looking for in players he brings to Minnesota.
"This is a good league, and it's really tough to be a point producer in this league. But if you swallow your pride a little bit and look at it from a little bit of a business aspect and where you are and what team you're on and what role you can fill, you've got to put that draft pick stuff aside," Guerin said. "The sooner that guys can do that, they get it out of their own head where they're 'supposed' to be. Young players fail to make it in the league because they're not willing to bet like a guy like Ryan is.
"He's accepted what he is in this league. A lot of players don't, and that's why they don't play."
Hartman has been so good at what he has become that he was almost becoming too good.
Valued for a similar role he held with the Philadelphia Flyers in 19 games in 2018-19, Hartman was traded after the season to the Dallas Stars because the Flyers were afraid of what he'd command in salary arbitration as a restricted free agent.
Dallas didn't qualify him an offer, which made him free to sign with any team.
