More than he even knows.
"He's had a huge impact," Fehr said. "Everybody in the room loves the guy. He's brought a positive attitude toward the room. He's not really a rah-rah guy. He's not standing up having big speeches, but he knows the time and the place to make some comments and make sure that the guys are prepared. Even the young guys feel comfortable talking to him about stuff. That's great when you have a guy that can come in and make such a big difference in the room."
Speaking of the young guys, 24-year-old rookie left wing Conor Sheary said Cullen was great to him.
"You can talk to him any time you want," Sheary said. "He's always open to giving you insight. If you're working on stuff in practice or whatever it may be, he's been really good like that."
Sheary said he used Cullen as motivation.
"It's awesome and it's encouraging for a young guy to see you may have the opportunity to play as long as he has," Sheary said. "If you see his work ethic you would know why he's still playing."
Cullen still has to make up his mind if he wants to keep playing.
"I don't know. I don't know," he said. "We're going to sit down at home. I don't know. This is awesome. You can't top this, but we'll just think about it a little bit. I just want to soak it all in."
That wasn't hard Sunday. His kids were around him, playing around, having a blast. The Stanley Cup was nearby. It was his again, 10 years later.
"I felt really fortunate to be a part of that first one, it was a special group, a special season and you just don't get those kind of opportunities very often," Cullen said. "I would have been really happy with the career I had. I've been really fortunate to play as long as I have. Now to get this, I couldn't ask for something more than this."
