Goalie Carter Hart returned from an extended absence because of a lower-body injury and stabilized the crease down the stretch, going 6-0-0 with a 1.66 goals-against average and .930 save percentage after Tortorella took over.
The Golden Knights play Game 1 of the first round against the Utah Mammoth at T-Mobile Arena on Sunday (10 p.m. ET; Utah16, SCRIPPS, ESPN, SN, TVAS, CBC).
"Well, I mean, let's call it what it is, they're getting goaltending," Olczyk said. "Every time I turn on a game Carter Hart is playing and they are getting saves, and that's something big for a team when you do have the confidence that the guy is seeing it and he's feeling it and you're not giving up 15 scoring chances a game. You're giving up maybe nine or 10 and you'll take your chances with that. So they've gotten goaltending and they've buttoned it up.
"They couldn't be playing any better going into the playoffs, that's for sure."
They'll be challenged by Utah, though.
The Mammoth are in the playoffs for the first time in their second season since the franchise moved from Arizona. They had 92 points and won two of three games against the Golden Knights, including 4-0 in their last meeting March 19.
Olczyk said a big reason he believes in the Mammoth is goalie Karel Vejmelka, who won 38 games and finished with a 2.75 GAA and .897 save percentage in 64 games, including 63 starts.
He will be making his first appearance in the Stanley Cup Playoffs.
"I'll say this about Utah, they've got a guy in goal that looks like he has the ability to win a playoff series," Olczyk said. "He looks like he has that type of gene. He can win you games and if you can do that, it's going to win you series. That to me is a huge positive for a team that doesn't have a lot of experience."
The Mammoth had a League-high six players with at least 20 goals, including forwards Dylan Guenther (40), JJ Peterka (25) and Logan Cooley (24), who each will make his NHL postseason debut.
The other three -- forwards Nick Schmaltz (33 goals), Clayton Keller (26) and Lawson Crouse (24) -- have played in a combined 22 postseason games. Keller and Crouse have never played an NHL postseason game in front of fans.
They were part of the 2020 playoffs, played without fans because of the COVID-19 pandemic.
Schmaltz's only playoff appearance was four games with the Chicago Blackhawks in 2017.
"But you do have a guy in (defenseman Mikhail) Sergachev, who has been through the ringer a few times in Tampa," Olczyk said. "(Defensemen) Ian Cole and Nate Schmidt too. I mean, look at their left side, Cup winner, Cup winner, Cup winner. I think that really helps.
"Now guys will realize really quick that it feels like the other team has six guys on the ice when it comes to playoff hockey. The rink feels smaller. You do have time but you understand that every shift can be the difference. … They'll learn it. They'll get through it. They'll realize, 'OK, this is way different.' "
Olczyk thinks the Mammoth will adapt quickly because he expects Utah and Vegas to play a long first-round series.
"They're going to have to have their fastball, but it's a heck of a matchup," he said. "It should be great theater, especially going back to Salt Lake for the first time in the playoffs."
