Traded to the Penguins by the Carolina Hurricanes on Feb. 23, Hainsey, 36, enjoyed a Stanley Cup Playoff ride that ended with him hoisting the trophy he had so coveted during his 14 NHL seasons.
Now here he was, receiving his championship jewelry after helping defeat the team he'd won it with.
"It was very nice," Hainsey said. "What can you say, it's a special place, special organization, from ownership down. There are people over there who I've known since I was 8 years old and obviously got to know a lot more in my short couple months. Special place, special team for sure."
Hainsey, who signed a two-year, $6 million contract with the Maple Leafs on July 1, said the Maple Leafs have improvements to make to reach the Penguins' heights.
"We still have a long way to go, and it's early," he said. "But guys are learning and you can see it's pointed in the right direction."
The Maple Leafs aspire to be what the Penguins are. A victory at the home of the two-time defending Stanley Cup champions shows they are taking steps, however small they might be, in that direction.
Motivation was everywhere the Maple Leafs looked, whether it be Hainsey's ring, the yellow-and-black Stanley Cup banners dangling from the rafters or just the sight of Sidney Crosby, who has won the Conn Smythe Trophy as playoff MVP two consecutive times.
"To come here and win against a team like that, in their home rink, with those championship banners up there, it's big," said Maple Leafs goalie Frederik Andersen, who made 33 saves. "It gives you an idea of where you are and how far you still need to go to reach your goal."
Andersen said seeing Hainsey's ring should stoke the desire of his teammates to accomplish the same thing.
"I remember when I was in Anaheim (2013-16), I saw Dustin Penner's two rings, one that he won with the Los Angeles Kings (2012), the other with the Ducks (2007)," Andersen said. "It drives you. You see one and you say, 'I want one of those.'"
