He has seven points (two goals, five assists) in 11 games, tied with Matvei Michkov (six goals, one assist) for Philadelphia's scoring lead.
"He's just kind of a happy-go-lucky guy," Martone said of Zegras. "He cares so much about this team, and he just loves coming to rink. ... There's going to be adversity in the season; he's someone who's going to lighten the mood in the room. It's awesome to have one of those guys on this team."
Zegras sees his leadership approach as paying forward what older players did when he began his NHL career with the Anaheim Ducks in 2020-21, crediting defenseman Josh Manson for being one of his earliest mentors.
"I didn't live with him, but he was the guy that really I felt like went out of his way to look out for me," Zegras said.
Manson said Zegras was an easy player to help.
"I felt like the League was pumping him, there was all this hype around him," Manson said. "He's a guy that as much as he looks like he likes the spotlight, he's a flashy kind of personality, I think he also likes his private space a little bit and he just wanted to come into the League and do his thing and prove himself.
"I just wanted to be there as a normal, level-headed ... you've got something on your mind, you can bring it to me any time you want and I'll give you advice on it, whatever it may be. ... For anybody who's young in the NHL, it's a tough league. It's a tough league to crack, so sometimes you need a sounding board."
Zegras has since become that sounding board for younger teammates.
"You don't want to go out of your way to start saying stuff to everybody, but if there's questions and things I think I can help with, I don't mind sharing,” he said. “It's fun."
His teammates are certainly appreciative.
"I feel like in hockey, there's not a lot of people that are like him," Barkey said. "He's one of a kind in my eyes, and I think you can learn a lot from him and just how he carries himself and what he does day to day. I think his mindset, his vibe, his attitude, just the way he talks to me, it helps me take my mind off hockey when it needs to be taken off hockey.
“And he's also there for advice. He's been through it. He's been in the League for a long time, so I can kind of reach for him and ask him questions. And two different facets, whether it's life or hockey."
