"Obviously, that was after kind of a tough loss, and you want to keep him encouraged because that's a pretty big stage, the World Juniors in Canada," Holtby said. "So for a young kid to have that pressure, you want to make sure he knows he's doing all right and just keep going."
Hart said he and Holtby talked about handling adversity, including some reminders about lessons they have learned from Stevenson.
There also was a bit of good-natured kidding.
"He said, 'Good luck going all the way even though you're a Flyer,'" Hart said. "There's that Washington-Flyers rivalry there a little bit."
Stevenson said Hart gave him a few more details about the conversation: "At the end, he says, 'Mr. Hart, you're a Philadelphia Flyer and when I meet you I'm going to kick your [butt].'"
Future NHL rivalry aside, Hart said having a relationship with Holtby and Stevenson will benefit him as he starts his professional career this season.
"I don't really know [Holtby] that well," Hart said. "I'll hear from him every now and then, just a text. That's pretty cool to have a guy like that you can talk to. Entering my first year pro, I was going to talk to him about expectations and about your first year of pro hockey and what it's about in the transition from junior to pro. I think it's pretty cool that he's open to talking about that."
Hart has done well since that WJC loss. He was named Western Hockey League goaltender of the year after the 2016-17 season, the second of three consecutive seasons he won the award with Everett. Last season, he was in net for Canada when it won gold at the 2018 WJC. And in addition to winning his third straight WHL goaltending award, he was named the top goaltender in the Canadian Hockey League.
Hart, selected by the Flyers in the second round (No. 48) of the 2016 NHL Draft, likely will start with Lehigh Valley of the American Hockey League. With veterans Brian Elliott and Michal Neuvirth unsigned beyond this season, he could be the Flyers' long-term answer in net.
Hart isn't concerned by that now. He's leaning on a mantra Stevenson taught him when he was 10 years old: "I have no future. I have no past. My goal is to make the present last. I'm right here, right now."
"You just have to control what you can control," Hart said. "You can't control what other people think about you, what the staff thinks and their decisions. But what you can control is how you conduct yourself and how you prepare and all the little details with your game. I think that's where your focus has to be."
Hart has been impressive during training camp with a 1.74 goals-against average and .947 save percentage in two preseason games. He made 25 saves on 27 shots in 40 minutes of a 6-4 win against the New York Rangers on Wednesday, including 17 saves on 18 shots in the third period. He also made saves on all 11 shots he saw in 29:55 of ice time in a 3-1 win against the New York Islanders on Sept. 17.
"He's not an overactive guy in the net, especially for a young guy," coach Dave Hakstol said. "He is very calm and doesn't make anything look too difficult because he is settled and really good and sound."
