Breaking down the criteria of the award, to Cullen, perseverance means playing for a long time and being able to stick around in this league despite being 42 years old.
"I'm proud of the fact that I can still play and I'm part of something special," he said.
When it comes to sportsmanship, Cullen feels that's mostly about being a good teammate. And he's not just a good teammate, he's the best teammate. Everybody Cullen plays with absolutely adores him, and couldn't speak more highly of him as a player and a person.
"I think that's something I've always tried to do, is be a good teammate and go out of my way for other guys," Cullen said. "I don't know all the nominees, but I can probably think of a few. And when you look at all those guys, those are guys that everybody wants on their team."
As for Cullen's dedication to the sport of hockey, his 1,500-plus games played speaks for itself. He's certainly managed to adjust and adapt in different facets, from accepting different roles to paying more attention to his health as he aged.
But for Cullen, the real secret to his longevity is quite simple.
"I think the biggest thing, honestly, is that I just love to play the game," he said. "Everybody takes care of their nutrition and trains, and I've done that throughout my career. But I really enjoy the competition. I love the battle and I love this time of the year. It's worth working out and training and battling to get to this point in the season where games really mean a lot and every play is really important. To me, that's the biggest thing. I just love that."
Cullen admitted with a laugh that it would be fun to take the family to Las Vegas for the annual NHL Awards, joking that he could "show the kids a few things at the blackjack table." But no matter who ends up a finalist, Cullen really is honored to even be amongst the 31 nominees around the NHL.
"There are so many great stories in our league, whether it's coming back or being around for a long time or some guys who don't get their shot until they're 30," he said. "There's just so many good stories of good people that persevere and work hard to get to here. For me, I'm honored to be in that group."
