They became teammates with the Sharks more than a decade ago, won a gold medal for Canada at the 2010 Olympics and each had their captaincies stripped as they became the faces of so many postseason failures in San Jose.
Now at age 36 and after more than 3,000 combined games, 949 goals and 2,610 career points in the regular and postseason, Thornton and Marleau have the opportunity to add the only thing missing on their impressive career resumes if they can win the Stanley Cup.
"It’s just the next step for us," Thornton said Friday. "We’ve been doing a really good job of staying day to day, shift to shift. This is just another challenge we’re hoping to come out on top on."
The two will take the ice in the Stanley Cup Final for the first time in their careers on Monday night in Pittsburgh, ending a long journey that included many disappointments and criticism that was often undeserved.
"It’s two legends," teammate Brent Burns said. "I’ve said it before. Those two are some of the best players to ever play the game. It’s huge to get them here. They’ve done pretty much everything else. They sometimes take a bad rap in the media, which is unnecessary. Anybody that’s played with them sees the way that they work and what kind of teammates they are, what kind of people they are. They’re two of the best."
They just haven’t always been considered that way because of the lack of playoff success that was at times as much a reflection on the lack of help they got as it was on any deficiencies in their games.
But both also had times when they failed to raise their game at the biggest points of the season. Thornton went pointless during a seven-game series loss to Montreal in his final playoffs in Boston in 2004 while he played with torn rib cartilage. Thornton also posted a -11 rating in the 2010 playoffs in San Jose when the Sharks got swept by Chicago in the Western Conference final.
Marleau struggled in the 2007-09 playoffs when San Jose got knocked out twice in the second round and then lost as the top seed in the first round to Anaheim in 2009. That led to the Sharks demoting him from captain.
The two have had plenty of playoff success along the way as well, but it has been the failures that colored people’s perceptions of them, none more than blowing a 3-0 series lead to Los Angeles in 2014 in a collapse that ultimately led to Thornton being stripped of the captaincy.
"We’ve been through a lot here," teammate Logan Couture said. "I’ve only been here seven years but those guys have been here longer than I have and they deserve this. They’ve been through a lot, Patty especially."
Marleau played 165 playoff games before reaching his first final, the most of any player. He lost his first three trips to the conference final and needed 16 trips to the playoffs to reach the final round.
Thornton was next on that list with 150 games, including two conference final losses before making it to the Cup in his 15th postseason.
The fact they will be there in Sharks uniforms only makes it more special. There was talk they could be traded the summer after the 2014 playoff collapse, Thornton had a public feud with general manager Doug Wilson last season and there were reports that Marleau was seeking a trade earlier this season.
Nothing ever materialized and the two are still in San Jose to the delight of all sides. Thornton is playing perhaps the best two-way hockey of his career, posting three goals and 15 assists through the first three rounds and dominating possession against the other team’s top players.
After spending much of the year as a third-line center, Marleau moved back to his more familiar spot of a second-line wing alongside Couture. He has four goals and eight assists so far, including two helpers in the third period of the conference final clincher against St. Louis.
"We’re just enjoying the ride right now," Marleau said. "We’ve had some really good teams over the years. This team is a little bit different. The confidence we’ve built over the regular season and now in the playoffs, I think winning on the road helped us get close as a group during the regular season. It carried over into the playoffs so far. Just having each other’s back out there, working for each other."
