No question. No team has repeated since the Detroit Red Wings in 1997 and 1998, and now the NHL has the salary cap, making it even more difficult. Nothing is guaranteed.
But the Penguins have become the third team to win the Cup multiple times since the salary cap was introduced in 2005-06, joining the Chicago Blackhawks (2010, 2013, 2015) and Los Angeles Kings (2012, 2014), and they seem poised to keep competing for the Cup for the foreseeable future.
Of the 25 players who appeared for the Penguins in the playoffs this year, all but two are 32 or younger. All but six are in their 20s, including their best players: Crosby and forward Phil Kessel, who are 28; and defenseman Kris Letang and center Evgeni Malkin, who are 29.
"We don't have an older team," Penguins general manager Jim Rutherford said. "We have a relatively young team."
Three players who appeared for the Penguins in the playoffs this year are pending unrestricted free agents, and they are forward Matt Cullen, 39; defenseman Ben Lovejoy, 32; and third-string goaltender Jeff Zatkoff, 29. Two are pending restricted free agents: forward Beau Bennett, 24, and defenseman Justin Schultz, 25. So the Penguins should not have to replace major pieces or deal with salary-cap headaches.
Coach Mike Sullivan established a strong identity of speed and skill after he took over Dec. 12, and if he got the players to buy in to win the Cup, you'd think he would have little trouble getting them to buy in to try to win it again. They saw it worked once; they'll believe it can work twice.
