Washington is playing its second Cup Final in its 43-season history. It was swept by the Detroit Red Wings in 1998.
"If you're there and get enough chances, eventually you're going to break through, and I think Washington is a great case of having a good team for a long time, and they've added on some more players and now they're deep as well," Sundin said. "Rightfully so, they're in the [Final], and they have a good chance now to win."
Toronto hasn't won the Stanley Cup since 1967, the last time it appeared in the Cup Final. The Maple Leafs have lost in the first round of the playoffs in back-to-back seasons after qualifying once in the prior 11.
"I think management has done a great job building the team and building an organization the way it's supposed to be done with lots of young players," Sundin said. "You see the Toronto Marlies now in the Calder Cup Finals and on the Maple Leafs roster, the best players are young, 20, 21, 22 years old, and if you keep building like that and adding on, you have a chance to be a great team for a long time."
Sundin was speaking at the delivery of his original Air Canada Centre banner, honoring his retired No. 13, to the Hospital For Sick Children. The Mats Sundin Fellowship, a foundation supporting an elite medical research exchange between the University of Toronto and the Karolinska Institute in Stockholm, specializes in research in child development and the first 2,000 days of life. Sundin said he plans to make a $1 million contribution in support of the program.
