Vegas turned out to be a great fit. He got an opportunity to play in more situations, and set NHL career highs with 50 assists and 66 points in 70 games. The Golden Knights went to the Stanley Cup Final in their inaugural season.
"That really gave me confidence, knowing that I could do it," Perron said.
St. Louis turned out to be an even better fit than it was the first two times.
Berube became coach Nov. 19, 2018 and put Perron in positions to succeed -- first power play, 5-on-3, 4-on-4, overtime.
"I think (it was) just making him understand how important he is for us and letting him know that, using him the way we used him starting last year," Berube said. "I think he's just increased his confidence, for sure."
Perron paired with O'Reilly, who wins face-offs, plays well defensively and makes deft passes, creating more puck possession, offensive-zone time and opportunities to score.
"The chemistry with O'Reilly right now, it's special, and I'm trying not to lose it," Perron said.
Perron had 46 points (23 goals, 23 assists) in 57 games last season, then 16 points (seven goals, nine assists) in 26 games in the Stanley Cup Playoffs.
This season, he has 49 points (21 goals, 28 assists) in 49 games, on pace for NHL career highs in goals (35) and points (82). He leads the League in game-winning goals (eight) and overtime goals (four) for a team tied with the Boston Bruins for second in the League, three points behind the Washington Capitals.
"He is a huge reason why we are in this position we are now," O'Reilly said. "The amount of not just points he's put up, but the significant goals he's contributed to … The overtime goals to get us these wins, I think, are monumental."
Asked for his memories of watching the All-Star Game as a kid, the first thing Perron mentioned was Owen Nolan calling his shot. That was 1997, when Perron was 8 and living in Sherbrooke, Quebec, and Nolan was playing for the San Jose Sharks at what was then San Jose Arena. Nolan put on a show for his home fans. Now Perron gets that chance.
"It was a different format," Perron said. "But I think the cool thing now, the way they do it with the 3-on-3 [tournament], if you win the first game, you might as well go for it, and you see the intensity really pick up in that final. And yeah, like, just seeing the best players play each other, and kind of getting introduced, the skill competition and so many things ... I don't know. Winning the Cup is definitely the biggest dream that you got, but that one's another one, for sure."
