The stat line was eye-popping: 30 completions on 36 attempts, 417 yards, and three touchdown passes.
When Saskatchewan Roughriders' quarterback Trevor Harris opened the 2026 season with one of the finest performances of his career, fans understandably focused on the throws, the reads and the execution. But behind every visible performance lives an invisible process.
That process, preparation, emotional control, focus, recovery, perspective and resilience, is where mental performance coach Dr. Chantale Lussier has quietly played a role for years. And for Harris, that work isn’t supplementary — it’s essential.
“I was trying to tell people, playing the game of football is at minimum half mental,” Harris said. “If we're being honest with ourselves, it's more than 50 percent mental. There's a lot of mental warfare that goes into it.”
In an in-depth conversation conducted by 3DownNation.com’s Justin Dunk and originally aired on the Rider Broadcast Network Countdown to Kickoff pre-game show on Saturday, June 13, Lussier offered a rare look inside elite mental performance and her long-standing work with Harris.
While she never claimed ownership of Harris’ success, repeatedly emphasizing the roles of coaches, teammates and the athlete himself, her philosophy provided insight into the foundation that helps high performers consistently show up when pressure is highest. For Saskatchewan fans watching Harris dissect the B.C. Lions in Week 1, some of those ideas looked familiar.
Lussier’s path into mental performance coaching didn’t begin on a football field. Before earning her doctorate and building a career in sports psychology and mental performance, she spent 12 years as a professionally trained ballet dancer and performing artist. Eventually, she returned to university to study sports psychology and had one immediate reaction.
“Where was this information when I could have used it as an artist and athlete?”
That realization launched what has become a two-decade career helping people perform under pressure. Her client list stretches well beyond football to Olympians, Paralympians, NCAA athletes, military personnel, police officers, surgeons, business leaders and performers. The common thread isn’t sport, it’s pressure.
“Whatever our craft is, whatever our domain of excellence is, all of us experience pressure and are trying to be the best version of ourselves,” Lussier said.
That phrase, best version of ourselves, should sound familiar to Roughriders fans. It mirrors language Harris often uses when discussing growth and preparation. For Harris, mental development requires the same urgency and commitment as physical training.
“If you're not training the mental side, then I think you're behind the eight ball,” Harris said. “I've said this offseason, as soon as you stop ascending mentally, you're a deteriorating asset, so I've tried to continue to press that pedal and work through that.”
Lussier often describes her work as taking place in “the mental gym.” For athletes unfamiliar with the process, she explained that sessions begin much like physical training or rehabilitation: assessment, understanding strengths, identifying areas for growth and building a deliberate plan.
The work is not random motivation; it is structured training. She described balancing long-term performance goals with the rhythm of a season, periods of peak performance, recovery and avoiding burnout. The objective is simple: be ready to perform without breaking yourself in the process.
Her framework for mental skills includes three broad categories:
• Cognitive skills such as focus, visualization, decision-making and self-talk.
• Emotional intelligence and self-regulation.
• Social responsibility and team energy.
Interestingly, Lussier identified emotional intelligence as one of the most overlooked performance tools.
“We all have emotions. If we don’t know how to use them, they might be our Achilles heel. But if we learn to use them, they just might become our superpower.”
That philosophy feels particularly relevant in football, a sport built as much on response to adversity as physical ability.
Lussier first met Harris in 2018 while working with the Ottawa Redblacks organization. She initially worked with players individually before being integrated into team operations through support from the sports medicine staff and then-head coach Rick Campbell. It didn’t take long before Harris reached out.
“It was clear there was an interest and curiosity in how we could learn from each other and how I could contribute to his journey.”
That relationship has now stretched across multiple organizations, seasons, injuries, recoveries and ultimately a Grey Cup championship. One of the themes Lussier repeatedly returned to while discussing Harris was curiosity. Despite accomplishments, despite experience, and despite entering football years when many quarterbacks are winding down, the 40-year-old continues to search for new ways to improve.
Harris admitted that some of the growth he wants can’t come from within football alone.
“A lot of the things that I want to get better at and ascend to, it's out of my professional realm and things that I know,” Harris said. “So I seek out somebody like her, and she's been great for me.”
Lussier called that openness a hallmark of greatness.
“The greats stay hungry, they stay open, and they stay curious.”
Some of her most detailed insights came while discussing injury recovery, an area that has become part of Harris’ football story. Her process begins with meeting athletes emotionally where they are: shock, frustration, fear and uncertainty. Then comes rebuilding. Visualization becomes a tool not just for performance but for healing. Mental reps become substitutes for physical reps. Eventually, the final phase arrives: does the athlete trust their body again? Does confidence match physical readiness?
Lussier credited Harris for approaching that process with determination and professionalism. She noted his return timeline surprised many observers. Importantly, she framed success not as toughness alone but as a combination of physical care and intentional mental work.
When asked specifically about quarterbacks and Harris, Lussier highlighted two mental skills.
The first: attentional focus. Not simply looking. Seeing. Quarterbacks must control what deserves attention and make decisions in real time amid chaos.
“The question becomes: am I truly seeing?”
The second: self-regulation. She used the metaphor of gears in a car. Different positions require different levels of activation. Too low and performance suffers. Too high, and decision-making disappears.
Elite quarterbacks learn how to find their gear. Cool. Calm. Composed. But ready to accelerate instantly. Watching Harris against B.C. in Week 1, those concepts appeared visible. Thirty completions in 36 attempts doesn’t happen by accident. Neither does operating efficiently while carrying expectations of defending a championship.
One revealing moment came when Lussier discussed Saskatchewan’s messaging entering 2026. The Roughriders have consistently said they are not defending champions; they are a new team. Lussier agreed.
“The scoreboard is going to be 0-0.”
Her message wasn’t to ignore success. Learn from it. Leverage it. But earn this year’s story. That mindset aligns closely with what Harris and head coach Corey Mace have consistently preached. No entitlement. No hangover. Just another opportunity.
Perhaps the most important takeaway from the interview wasn’t about football at all. Lussier challenged the idea that mental performance coaching exists only for crisis moments. She compared it to physical training: you don’t wait to get injured before going to the gym. Why wait to invest in mental and emotional performance?
For Harris, that investment remains ongoing. And after another reminder in Week 1 of what elite preparation can look like, it’s clear some of the most important work still happens far from the spotlight.
