PITTSBURGH - It wasn't supposed to take the San Jose Sharks this long to reach their first Stanley Cup Final. It wasn't supposed to take this long for Sidney Crosby to guide the Pittsburgh Penguins back to a destination many figured they'd become a fixture at after winning it all in 2009.

Not that either side is complaining.

Certainly not the Sharks, whose nearly quarter-century wait to play on the NHL's biggest stage will finally end Monday night when the puck drops for Game 1. Certainly not Crosby, who raised the Cup after beating Detroit seven years ago but has spent a significant portion of the interim dealing with concussions that threatened to derail his career and fending off criticism as the thoughtful captain of a team whose explosiveness during the regular season too often failed to translate into regular mid-June parade through the heart of the city.

Maybe the Penguins should have returned to the Cup Final before now. The fact they didn't makes the bumpy path the franchise and its superstar captain took to get here seem worth it.

"I think I appreciated it prior to going through some of those things," Crosby said. "I think now having gone through those things I definitely appreciate it more. I think I realize how tough it is to get to this point."

It's a sentiment not lost on the Sharks, who became one of the NHL's most consistent winners shortly after coming into the league in 1991. Yet spring after spring, optimism would morph into disappointment. The nadir came in 2014, when a 3-0 lead over Los Angeles in the first round somehow turned into a 4-3 loss. The collapse sent the Sharks into a spiral that took a full year to recover from, one that in some ways sowed the seeds for a breakthrough more than two decades in the making.

General manager Doug Wilson tweaked the roster around fixtures Patrick Marleau and Joe Thornton, who remained hopeful San Jose's window for success hadn't shut completely even as the postseason meltdowns piled up.

"I always believed that next year was going to be the year, I really did," Thornton said. "I always thought we were a couple pieces away. Even last year not making the playoffs, I honestly thought we were a couple pieces away, and here we are."

The Penguins, like the Sharks, are a study in near instant alchemy. General manager Jim Rutherford rebuilt the team on the fly after taking over in June, 2014 and with the team sleepwalking last December, fired respected-but-hardly-charismatic Mike Johnston and replaced him with the decidedly harder-edged Mike Sullivan. The results were nearly instantaneous.

Freed to play to its strengths instead of guarding against its weaknesses, Pittsburgh rocketed through the second half of the season and showed the resilience it has sometimes lacked during Crosby's tenure by rallying from a 3-2 deficit against Tampa Bay in the Eastern Conference finals, dominating Games 6 and 7 to finally earn a shot at bookending the Cup that was supposed to give birth to a dynasty but instead led to years of frustration.

True catharsis for one side is four wins away. Some things to look for over the next two weeks of what promises to be an entertaining final.

FRESH FACES: When the season began, Matt Murray was in the minor leagues. Now the 22-year-old who was supposed to be Pittsburgh's goalie of the future is now very much the goalie of the present. Pressed into action when veteran Marc-Andre Fleury suffered a concussion on March 31, Murray held onto the job even after Fleury returned by playing with the steady hand of a guy in his 10th postseason, not his first. San Jose counterpart Martin Jones served as Jonathan Quick's backup when the Kings won it all in 2014 and has thrived while playing behind a defense that sometimes doesn't give him much to do. Jones has faced over 30 shots just four times during the playoffs.

"HBK" IS H-O-T: Pittsburgh's best line during the playoffs isn't the one centered by Crosby or Evgeni Malkin but Nick Bonino, who has teamed with Phil Kessel and Carl Hagelin to produce 17 goals and 28 assists in 18 games. Put together when Malkin missed six weeks with an elbow injury, the trio has given the Penguins the balance they desperately needed after years of being too reliant on their stars for production.

POWERFUL SHARKS: San Jose's brilliant run to the Finals has been spearheaded by a power play that is converting on 27 percent (17 of 63) of its chances during the playoffs. The Sharks are 9-2 when they score with the man advantage and just 3-4 when it does not.

OLD MEN AND THE C(UP): Both teams have relied heavily on players who began their NHL careers in another millennium. Pittsburgh center Matt Cullen, who turns 40 in November, has four goals during the playoffs. Thornton and Marleau, both 36, were taken with the top two picks in the 1997 draft that was held in Pittsburgh while 37-year-old Dainius Zubrus draws stares from younger teammates when he tells them he used to play against Hall of Famer (and current Penguins owner) Mario Lemieux.

"When I say 'Twenty years ago I was playing against Lemieux, they say 'I was 2-years-old,'" Zubrus said.
