During an eventual 5-4 Blues overtime win against the Sharks on Thursday night, the scoreboard whispered untruths that San Jose had sealed the game by opening up a three-goal lead entering the third period.

The numbers on the screen said the Sharks dominated the second period and that the remaining 20 minutes could be a formality, the final crowning moments of a night Sharks fans would remember for Macklin Celebrini’s debut. The lead was too much, the time was too few, the comeback too fictional.

The Blues made sure the scoreboard had some explaining to do.

In scoring the final four goals of the game, the Blues roared back from a 4-1 deficit entering the third period to snatch an overtime win thanks to Brayden Schenn’s goal 45 seconds into overtime. Radek Faksa, Ryan Suter and Justin Faulk (game-tying, extra-attacker goal with 47 seconds left in the third period) each scored in the third period, supporting Pavel Buchnevich’s first-period goal.

“We’re playing for one another,” Schenn said. “I know it’s early and it’s only two games. We have a lot of new faces in here. We have a good feeling in our locker room where guys are playing for one another. Guys are speaking up. Guys are bringing energy. Guys are playing together.”

The victory piggybacked on Tuesday’s come-from-behind win in Seattle, a 3-2 win in which the Blues erased a 2-0 Kraken lead in the second period and shut them down in the third period. It was the second time in franchise history (also 2009-10) that the Blues won the first two games of the season by coming from at least two goals down.

It was also the fifth time the Blues won a game when trailing by three goals in the third period, with the most recent coming last December against Chicago — coincidentally another game against a No. 1 pick enjoying a signature moment.

“Here tonight is proof of how we need to play,” Blues coach Drew Bannister said. “All you have to do is sit back and watch the first and the third period, and what we did, what we were able to create. We played on the offense, we were aggressive, we attacked, we forechecked, we defended quickly. That’s the way our team has to play.”

Thursday unfolded in three distinct acts.

The Blues owned the first period. The Sharks controlled the second. The Blues wrestled back the third and possessed overtime.

In the first period, the Blues pounded San Jose with 22 shots. It was the first time in more than a decade (March 25, 2014) that St. Louis had at least 22 shots in a first period, and despite that, the Blues entered first intermission down, 2-1.

Celebrini scored his first career goal by banking a pass off Matthew Kessel’s skate, and then set up Tyler Toffoli’s goal with a pass from behind the net. San Jose had the lead, but the run of play forecasted that it wouldn’t have it for long.

But the Sharks pushed back in the second period, outshooting the Blues 17-7 and scoring both a power play goal and a shorthanded goal. They opened a three-goal lead in front of a juiced up crowd for a home opener, and submitted a middle period that harkened back memories of last year’s Blues’ failures against the Sharks.

The Blues dressing room during the second intermission wasn’t hushed.

Schenn: “The room wasn’t quiet in the second intermission. There’s some guys with positive energy in here. There’s no sense being negative about what’s happened. They got two goals on tough bounces and we had a good first period."

Faulk: “We had a good first period, we had a lot of chances. We thought if we could replicate that and go back out and get some chances like that, start with one and continue on. I don’t have exact words, but it was just holding us accountable and telling us ‘it’s not good enough.’ Guys knew it. Guys said it to each other a bit.”

Bannister: “Just we’ve got to get back to playing the way that we need to play to have success. Sometimes when things don’t work out in the first period, even though you’re playing really good hockey, you tend to get away. And we got away from our game. Then we end up in a hole that we’ve got to dig ourselves out of. Good on them to realize we’ve got to get back to work here and play the way we need to play to have success. Now they see that.”

The fourth line of Faksa, Alexey Toropchenko and Nathan Walker led the way in the third period. The first two goals were a direct result of work done by the line, tallies that helped inject more belief in the Blues’ group.

They helped bury the 0-2-1 record against the Sharks from last year.

“All in all, it wasn’t the feeling of what we had last year against this team,” Schenn said. “It felt like we actually played hard and generated lots, but once we got back to our game of being north, direct, that’s how we got all the goals.”

The Blues did not capture their second win when allowing the first goal until Dec. 16 last year. They didn’t win their second game when trailing by two goals until Dec. 23 last year.

This year’s Blues have discovered their resiliency before any other team in the NHL, and for a team welcoming in seven new players on its roster, that could go a long way to pushing their season in the right direction.

Even if they had to fall behind to do so.

“You could tell guys weren’t just shut off,” Faulk said. “They weren’t happy with what was going on. They were getting frustrated. To an extent, that’s good, right? You’ve got to find some emotion and play this game with emotion. As soon as you don’t, it can go sideways.”
