For Nurse, the transition to an even bigger role is not dramatic for him.
"I'm just playing, to be honest with you," he said. "Not thinking much, just playing. Obviously, I don't want to be running around too much, getting myself too tired."
Paying close attention to how some of the League's top defensemen handle big minutes, being wise about conserving their energy during shifts when possible, has helped Nurse.
"I've watched those guys in the summers, watch some of their tape," Nurse said. "There's a time to go, a time to stay back and you've got to be able to be a little more conscious of it when you're playing against better competition. Each shift matters. You have to have the awareness of all parts of the game.
"I can skate forever, it feels like. When you get into the corners and you battle, you probably exert yourself a little more. So, it's about being conscious of it, that when you get into a battle, you don't want to just go jumping into the rush 45 seconds into a shift."
Playing big minutes was the norm when Nurse played junior for Sault Ste. Marie of the Ontario Hockey League from 2011-14.
"I remember our last playoff series when we played Connor, and it (ice time) was up there then, chasing him around," he said. "There are similarities (to junior), but everything at this level is escalated. Everything has a little more intensity to detail. But you don't want to change your game too much, you just want to play. That's how I've been taking it. It's why you work out in the summer, to be able to handle situations like this."
Larsson played with Nurse as his partner last season, when Klefbom missed 15 games with a shoulder injury. He said that familiarity helps, as does Nurse maturing as a young defenseman that's ready for the challenge.
"He's been playing really good," Larsson said. "You can see he's getting a lot of power-play time and that kind of gets his confidence up. He and (Klefbom) are similar players. Nurse is maybe a bit more aggressive, but other than that, I don't think it'll change a lot.
"I played a lot with Nurse last year, too, so I'm familiar with him and that's an easy adjustment. He's got a good defensive mindset and it makes it a lot easier in the D-zone. He's a key guy on this team and we need him at his best and I think he's been playing really well lately."
