For the first 40 minutes of Saturday's game in Tampa Bay, the Sharks had the Lightning within their reach. Sure, San Jose went into an early 1-0 hole, but they kept grinding in an effort to even up the score.

But after finding themselves down 3-0 in the waning minutes of the second stanza, the Sharks' effort took a backseat on their way to losing 7-1. It collectively became a game San Jose wants to put in the rearview mirror as quickly as possible, but also served as an important lesson as the Sharks continue to iron out mistakes.

"It was a strange game," head coach Peter DeBoer told reporters at Amalie Arena after the loss. "At the end of 40, I was pretty happy with how we were playing. I didn't think we deserved to be down 3-0, but that was the reality. The third period was just unacceptable. A poor, poor effort. I think instead of sticking with it we started feeling sorry for ourselves after that fourth goal and maybe started thinking about tomorrow and you can't do that in this league. Throw that one out."

Logan Couture agreed with DeBoer's assessment.

"I thought we played pretty well through two, I thought we had some good five-on-five looks," Couture said. "I didn't like our third period. We gave them some many freebies and let our goalies down. For the first 40 I thought we played hard, it could have been a one or two-goal game."

San Jose generated a couple of good looks in the first 40 minutes, with a Kevin Labanc chance in the second being the best. But through two periods -- and most of the third period -- San Jose was unable to find the back of the net.

"I don't think we started as bad as maybe the score was telling us," Erik Karlsson said. "That's the way it goes sometimes."

Bolts' netminder Andrei Vasilevskiy stood tall as he came within minutes of handing the Sharks their first shutout loss of the 2019-20 season, but Couture insisted San Jose didn't put enough pressure on him.

"He played well, he made saves, but I think we could have done a better job with traffic," Couture said. "There were second opportunities around him and they did a good job of boxing us out. We've got to be hungrier around their net to score goals."

Even though the Sharks seemed content overall with how they play through the first two periods, there's no denying that the first five minutes set a tone for the rest of the evening. The Sharks were granted six minutes of power-play time thanks to a tripping penalty on Ondrej Palat 15 seconds into the game and then high-sticking double minor on Mathieu Joseph a little over five minutes later. San Jose couldn't convert on any of their chances, stretching their power-play goal drought to a ghastly 0-for-22.

While the power play isn't the only thing the Sharks have to correct after Saturday's loss, it has definitely raised concern.

"I've been trying to be patient through it," DeBoer admitted, "but it hasn't been good and it's getting to the point now where, tonight a big difference in the game was special teams. Especially when we get those early ones, that's a chance to grab some momentum on the road."

The Sharks are fortunate enough to have a quick turnaround after Saturday's loss, heading to Sunrise to face the Panthers in a Sunday matinee.

"Overall, I think this is a game we're going to have to learn from," Karlsson summarized. "We've got to figure out a way to be successful no matter who we are playing. Today was a tough one on the score sheet, but we have a game again tomorrow. We have to fix the things that make us successful."
