"I think it was just raising his standard, raising his bar," Chiodo said. "That's in his preparation. It's just the way he handled himself every day. I think that was even socially, picking his spots, making the necessary sacrifices he needed to make to just be the player he wanted to be.
"That first summer was great. I mean, it was powerful. We knew something special was going on."
That's why it was hard to swallow when the Blues considered him a fourth-stringer in 2017-18. They didn't have a spot for him in the AHL because they were sharing an affiliation and ended up sending out a memo asking if anyone needed a goalie. He reported to Providence, the AHL affiliate of, of all teams, the Bruins.
Despite the circumstances, his goals-against average dropped from 2.71 to 2.05 from season to season, and his save percentage popped from .911 to .926.
"What he knew, and I guess we knew, was that his game was in an awesome place, and he was about to have an awesome season," Chiodo said. "And he did."
The Penguins hired Chiodo as a goaltending development coach on June 20, 2018. But he and Binnington kept working together.
The Blues sent Binnington to San Antonio of the AHL to start this season. He went 11-4-0 with a 2.08 goals-against average and .927 save percentage, then came up to St. Louis and went 24-5-1 with a 1.89 GAA and .927 save percentage. He's 12-8 with a 2.40 GAA and .915 save percentage in the playoffs.
Chiodo raved about Binnington's resilience and character.
"I would say his mental strength and mental makeup is at a completely different place than it was," Chiodo said. "I would say his belief in himself is in a completely different place than it was. His strength and mobility [have improved]. His on-ice game, there's a couple things that he feels much more confident about.
"So it's just, he upped his level. He upped the standard in five or six different areas. They all kind of culminated together to help him play at a high level for what's been really two full seasons now.
"It gives me chills thinking about where he's come."
