Giroux especially. Their friendship dates back to when they were teammates with Canada at the 2008 IIHF World Junior Championship. They didn't play together often 5-on-5 with the Flyers, but Giroux always knew Simmonds had his back on and off the ice.
"I think it was multiple times where he kind of made me feel safe or made me feel like we were all in this together," the Flyers captain said. "When I had my really bad season three years ago (58 points in 2016-17 after offseason hip and abdominal muscle surgery, I think Wayne was one guy that really supported me, kind of made sure I was OK. That's the kind of teammate he is.
"When he's in a scrum guys are a little bit more on their heels. He's got that presence that he might get angry and you don't want to get him angry. Every time he'd get angry, I'd go up to the other guys and say you just messed it up, you got Wayne Simmonds mad. His presence, in a physical game, it's not easy to miss."
Simmonds' work ethic also was easy to see, and a touchstone for younger players.
"He's done so many things in his eight years here that were so unselfish," Giroux said. "It was easy to see that he wanted to be a great teammate and he was a great teammate. But there's things that really make you think this guy is really unselfish and he cares about the team more than himself. It was easy to see."
Giroux was excited about what Hartman could bring. The 24-year-old forward had 20 points (10 goals, 10 assists) in 64 games with the Predators, and was fifth on Nashville with 69 hits. With the Chicago Blackhawks in 2016-17, he scored 19 goals -- 18 at even strength -- while averaging 12:46 of ice time.
"He's a very smart hockey player," Giroux said. "I think his hockey IQ is very high. He's got some skill, some grit. ... Orange and black is going to look good on him."
