Before traveling to New York on Wednesday, coach Mike Sullivan said Carter has provided the locker room "a little bit more swagger." He's also given the Penguins the center depth they've lacked since losing Nick Bonino in the 2017 offseason.
"On any given night, any line can score," Sullivan said. "Any line can help us offensively. We have lines that we can utilize in different situations depending on what's called upon during the course of a game. So I think [Carter's] addition has been huge to our team."
With second-line center Evgeni Malkin back from an undisclosed injury that held him out in the first two games of the series, Carter is the third-line center with left wing Jared McCann and Frederick Gaudreau. He said he's grown into the role smoothly.
"To be honest with you, I really didn't know where I was going to fit in coming in, whether it was wing, center, whatnot," Carter said. "But I think, as I've settled in and played with some different lines and whatnot, I think I've really enjoyed my role. … It's been a real easy group to come into. When you get traded sometimes, it takes a while for guys to get comfortable.
"Everybody was great. As a new guy coming in, when you feel comfortable in a room as quick as possible, it kind of accelerates the process."
