When he won his first of two Stanley Cups with the Pittsburgh Penguins in 2016, he was certainly riding off into the sunset ... until he came back and won another Cup, playing a team-high in minutes among Penguins forwards in the deciding Game 6 of the Cup Final in Nashville last spring.
Once again, talk of retirement lingered until he signed back on with his hometown Wild last August.
Following a rocky start to his homecoming, Cullen's game has slowly built as the magnitude of the games has increased.
"Here's a guy thats won two Stanley Cups in a row. I don't think the first 10 games of the season is gonna make or break him," Boudreau said. "But now you can tell, he's ramping it up. Hopefully this is a regular thing because he's scoring fairly regular right now."
Tyler Ennis, who assisted on Cullen's goal on Friday, said he's seen a pep in the veteran centerman's skates as the season has worn on.
Now playing on his line, he's getting a chance to see it up close.
"I think this is why the Wild signed him," Ennis said. "When he was signed, I think it was really exciting for everybody because you sign a guy who's a great teammate and a guy that's won three Stanley Cups and knows how to win. This is the part of the year where he really ramps it up and it's awesome to be on his line."
That line was something special on Friday.
Cullen scored Minnesota's second goal, flashing quick hands on a quick move at the top of the goal, giving the Wild a brief 2-1 lead in the second period.
