"You're filled with pride seeing it go up, obviously being a part of it brings back a lot of memories. It's an odd feeling not being a part of it," Cullen said. "I think more than not you're just happy for what happened and you just kind of relive those experiences."
Luckily for Cullen, he was a part of a similar banner raising one year earlier, when the veteran centerman was back for his second season with the Penguins. He helped lead Pittsburgh to its first of back-to-back Cup championships in his first season with the organization.
Cullen will play against the Penguins for the first time since leaving during the summer on Saturday when the two-time defending Cup champions open a five-game road trip at Xcel Energy Center.
Now in his 20th season in the NHL, Cullen is back for a second stint with the Wild. He's played for eight franchises during that span, so playing against a former employer isn't a foreign experience to him.
Still, after playing two seasons in Pittsburgh and winning two Stanley Cups, Cullen admitted playing against the Penguins for the first time will be a special night for him.
"I think it will be different on an emotional level. I think there will be a lot more that goes into it as far as, I played [against] a lot of old teams I've played for previously," Cullen said. "But what we went through in Pittsburgh, seeing those guys again after everything that went on the last couple years, it'll be fun.
"On the hockey side of it, it's a challenge, just from an emotional standpoint. It'll be fun to go through it but there are challenges that come with that too."
It will also be a special night for his family. Cullen will receive his Stanley Cup ring in a small gathering, including his family, before the game. His three sons spent a bunch of time inside the Penguins dressing room the past couple of seasons, developing relationships with players there.
Cullen jokingly said he doesn't know which team his kids will be cheering for.
"It will be interesting to see what they're wearing for jerseys but they're excited to come to the game," Cullen said. "They had a pretty good set up in Pittsburgh and were at the rink an awful lot. Those guys are like a lot of uncles to them but it'll be fun, they'll be around."
Before that, Cullen is expected to have a few old teammates over to his house for a meal tonight.
"When you go through everything the past two years you get pretty close but there's always, you give each other a hard time," Cullen said. "But we keep in pretty close touch."
