Not nearly enough.
The Sharks lost 4-2 to the St. Louis Blues in Game 2 of the Western Conference Final at SAP Center on Monday. The best-of-7 series is tied 1-1 with Game 3 in St. Louis on Wednesday (8 p.m. ET; NBCSN, CBC, SN360, TVAS).
To Couture, this loss wasn't an isolated incident. The Sharks rallied from down 3-1 to defeat the Vegas Golden Knights in the first round, then won a back-and-forth, seven-game series with the Colorado Avalanche in the second round.
"In my opinion, that wasn't anywhere near what we're capable of, and I don't think we've played up to our capabilities in a while now," Couture said. "We did just enough to beat the Avalanche, but we haven't played our best hockey since that Vegas series.
"And it's discouraging, it's frustrating, because we're going to need everyone here if we're going to beat these guys, because they're a very good hockey team."

Coach Peter DeBoer disagreed that the Sharks hadn't played their best hockey since the Vegas series. But it's all how you look at it.
The Sharks have had good games, games when they looked like potential Stanley Cup champions, games like, well, Game 1 of this series. They forced turnovers, scored gorgeous goals and won 6-3 on Saturday.
But then they have had games in which they've looked out of gas or sloppy or both, games like this one.
We can all agree they haven't played their best hockey consistently. They haven't won back-to-back games within a series since the first round. Even then, they needed 58 saves in a 2-1 double-overtime win in Game 6 and had to rally from down 3-0 in the third period in a 5-4 OT win in Game 7.
"You can't hope to win a game," DeBoer said. "You can't put in enough effort to hope to win a game, and I think that's what we did tonight. I think you've got to make sure you're working hard enough that you're going to dictate the outcome."
The Sharks had just fallen behind 2-0 and taken a penalty in the second period when Couture knocked down a pass attempt by Blues defenseman Alex Pietrangelo at the San Jose blue line. He raced down the ice against Pietrangelo, protected the puck with his body, hit the brakes and slipped the puck past the left pad of goalie Jordan Binnington at 4:55, then shouted, "Let's go!"
"We needed a spark," Couture said. "We were pretty flat."
