Because if they don't, they will find themselves in rare company -- and on summer vacation.
Twice has a team never led in a game in a best-of-7 Stanley Cup Final. In 1952, the Montreal Canadiens never had a lead against the Detroit Red Wings, and in 1960, the Toronto Maple Leafs never had a lead against the Canadiens, each series wrapping up in four games.
Needless to say, the Sharks would prefer not to join that company.
So the game plan for Game 5?
"Score first," Logan Couture said. "Go from there."
And despite all evidence to the contrary -- the lack of leads, the speed of the Penguins, the sheer fact that they're on the edge of elimination -- Couture said the team, like its coach, has faith that this series is not yet over, or won't be Thursday after Game 5 (8 p.m. ET; NBC, CBC, TVA Sports).
"We're going to battle to the end," he said. "We're confident we can go there and win a hockey game."
Though they got down early -- again -- in Game 4 at SAP Center, the Sharks -- again -- did not lie down in the third period. They pressed late, getting within one goal at 8:07 of the third, when Melker Karlsson scored while falling to one knee. But that one goal was far from enough, not after the Penguins scored once in the first (Ian Cole, 7:36) and once in the second (Evgeni Malkin, 2:37 on the power play), before icing the game with an Eric Fehr goal at 17:58 of the third.
"Most of the postseason we've been able to jump out [to leads]," Sharks captain Joe Pavelski said. "We haven't quite got that yet. Moving forward, I think that's going to play a big role in giving ourselves a chance. If we can get going that way, it's going to help."
