Just as it has been going better for the Blues lately.
St. Louis is 4-2-1 in its last six games, lifting the Blues (20-21-5) from last place in the Western Conference on Jan. 5 to four points out of the second wild card spot into the Stanley Cup Playoffs.
Perron has been instrumental in that rise.
"Just a confident player more than anything," Berube said. "I think he's a skilled guy. He's got real good vision and puck skills, but he's real confident right now. He's feeling good with the puck and when he gets the puck on his tape, he hangs onto it and makes plays and he's really strong on it."
Some of that confidence has come from those talks between player and coach, when Perron got to express himself -- and feel that he'd been heard -- even as he felt "blind-sided" by the scratch itself. He hadn't felt the situation was as dire as Berube did, a few bad penalties and a few poor decisions notwithstanding.
"The only reason I brought this up to him is I think coaches a lot of times they have so much on their plate to figure out their own teams, so they don't look around the League as much," said Perron, who has 479 points (192 goals, 287 points) in 767 NHL games during 12 seasons with the Blues, Edmonton Oilers, Pittsburgh Penguins, Anaheim Ducks and Golden Knights. "And I wanted to bring this up to him, kind of like, here was my role last year. Did everything go perfect? Absolutely not, but if you want me to be playing at a [certain] level, I think I can do it with this situation."
Perron had talked to forward Jonathan Marchessault about what he had been able to do when suddenly given opportunities with the Florida Panthers and then the Golden Knights, and how he'd risen to the occasion and succeeded.
He saw the same in himself in 2017-18, when he finished with an NHL career-high 66 points (16 goals, 50 assists) in 70 games for Vegas. Perron wanted to replicate that in 2018-19, now that he was back with the Blues for a third go-round after signing a four-year, $16 million contract on July 1.
He believed that, in Berube, he had a person he could open up to, a person who would listen to him, as long as he delivered his message in a respectful way. As he said, "I felt like I could push a little bit more than usual."
The response brought even more admiration from Perron toward his coach.
"I love the guy," he said. "I think I would go through a wall for him. He's been unbelievable for us as a team. He's brought us together. He wants us to compete harder, and even going through this situation with him showed me a lot about him and how he wants everyone to be on the same level on the team. It's great to see.
"We want nothing more than [to] keep turning our season around, making the playoffs and going on a run and give him the opportunity to be our coach moving forward too. He's in a spot where we know what he's at, and he's working so hard for us too."
