Mike Condon is perfectly suited to explain why it matters, and how it works. He lived it as an NHL goalie for 129 games over four seasons, then coached goalies for two seasons at Northeastern University after retiring. He went back to school to study the psychology behind it, earning a master's degree in counseling psychology and sport psychology from Boston University in 2025.
He now runs Condon Performance Consulting as a mental performance counselor for athletes and was invited by one of three former NHL teams, the Montreal Canadiens, to work with young goalie prospects at their development camp last summer.
"I like think of it as your brain and mind are like an iceberg, and the water level is your awareness," Condon said. "We know most of an iceberg is under the water compared to what is above the water. The conscious mind is above the water. There's a bunch of studies that say the conscious mind is only five percent of your brain. I don't know how they measure but the moral of the story is way more stuff is happening subconsciously below the water -- below your awareness -- than is happening consciously."
The conscious mind is for solving complex problems but also tends to seek relief from discomfort, uncertainty and fear. For a goalie, that creates problems after allowing a goal or when worried about making a mistake. The instinct is to think more, monitor movements more closely and try to exert control, but doing so can interfere with the automatic processes that make elite goaltending possible.
"If a player is coming down on a 2-on-1 and you're saying, 'Keep your glove up,' how much of your energy is focusing on where your glove is versus where his weight is on his blades or where his eyes are looking, or the cues other we rely on as goalies to read whether that player is going to pass or shot," Condon said.
Trying to consciously control movements that should be automatic can also compromise the movements themselves, said Condon, who has shown Cooley's clips to clients.
"When you have an automatic movement, something you already know, and you try to control it using the conscious mind -- because it wants to control it, especially if you don't feel good -- you're going to have clunky movements," Condon said.
Some neuroscientists have pegged the difference between how much information the brain processes in the conscious mind at 50 bits per second, while the subconscious mind handles the rest of the 11 million bits per second of incoming information. It's not hard to guess which part of the brain is going to react faster, especially when the subconscious mind is responsible for identifying patterns. That is essentially what goalies do in trying to read and anticipate such a fast-moving game with so many variables.
"It does make sense," Flyers goalie Dan Vladar said. "Obviously, everybody is a little different when it comes down to thinking about the game, but I think the basics are the same. Obviously less is more, especially when it comes down to your thoughts."
Most just don't discuss it as openly and enthusiastically as Cooley after a game.
"I'm not a type of guy that would come out saying it publicly like that," Vladar said.
Some goalies are grateful that Cooley is going public. Some have reached out. Others, like Pittsburgh Penguins rookie Sergei Murashov, thanked him in a postgame interview of his own for being so open with his thoughts on the mental side of the position.
"I want to pass a media message to Devin Cooley," Murashov said after a 5-2 win at the Los Angeles Kings on Nov. 7, the 22-year-old's first victory of the season. "I saw he was really popular recently and I think most goalies (are) going through something like he's talking about, but not a lot actually speak (it) aloud. … Thank you to him, what he's saying, and it genuinely just helped me a little bit too."
Murashov isn't the only one happy for Cooley's candidness but as a fellow goalie, he knows thinking about not thinking is about a lot more than entertainment.
