But he spent 5½ seasons in the minors developing and fighting for his chance. He was 25 when he made his first NHL start. He's 26 now.
"I don't know what I expected, but I wanted to be in the NHL at the age of 20, 21, 22, 23, and it kind of wasn't working out," said Binnington, selected by the Blues in the third round (No. 88) in the 2011 NHL Draft. "It was a good lesson for me to learn experience-wise and understand that it's a privilege. When you get that opportunity, you've got to be ready, and I waited a long time for it."
He wasn't going to take playing in the NHL for granted, even after winning the Stanley Cup.
"I wasn't done," he said. "I had a lot to prove for myself, for my family. I felt like I deserved to be here. It's just I, like I said, had to learn a few things and gain some experience and just figure out more about myself. I think that comes with age."
Berube has seen a change since he coached Binnington with Chicago of the American Hockey League in 2016-17.
"He was kind of going through some things, but after that year, he became a better goalie," Berube said. "Definitely, there's a chip (on his shoulder), and I believe personally that's a great thing for a person to have."
Binnington has room for more growth. He's still learning the League, from the nuances of each rink to the tendencies of opponents. He's still learning how to manage his body and mind over the course of a full NHL season.
But he has grown perhaps the most important thing already.
"He's got many layers of skin, and I love that part of it," said former NHL goalie Darren Pang, the Blues TV color analyst. "He's been beaten down, and he's not going away. And I said this after 10 games last year. I said, 'This is not a fluke. He's not going away.' The layers of skin are a compliment to what he's been through."
Binnington will enjoy All-Star Weekend.
His grandmother Joanne Binnington will get to see him play in St. Louis for the first time. His mom, stepdad, two sisters and two stepsisters are coming too. Media day will be fun. So will the 2020 NHL All-Star Skills presented by New Amsterdam Vodka.
The game itself, though? He waited too long and worked too hard to take it lightly. Asked if this was a rare chance to relax and take in everything he has accomplished, he showed the same attitude he used to accomplish it.
"Yeah, but we've still got money on the line," he said about the game in which the winning team splits $1 million. "We're going to go for that. Yeah, I think just the media day and the skills competition will be a good time. Be loose. It's break, right? But then, yeah, come game time, we're going to hopefully bring home the dough."
