Being the youngest player on the ice was the first time Roy faced a significant challenge in his hockey career, but it was far from the last.
His shot, which is now considered the most potent weapon in his offensive arsenal, was weak according to Roy.
The solution? A sheet of plexiglass, hundreds of summer hours, and thousands upon thousands of shots. He also spent extra time at practice, working with his head coach at the time, Simon Larouche, painting the boards with the family black streaks that appear in almost every rink in Canada.
His conditioning would soon become a point of contention as well, but a change in scenery, as well as an added focus on structure and details, led Roy down a path that resulted in his selection by the Canadiens in the fifth round of the 2021 NHL Draft.
"When he arrived in Sherbrooke, he told the coaching staff he needed more structure, that he wanted to be coached," explained Sherbrooke Phoenix head coach and general manager Stéphane Julien.
They established a detailed game plan that focused on smart nutrition and proper conditioning, two of the biggest lessons most junior hockey players must learn before they're prepared to take the next step.
It's one thing to ask for help, but it's little more than lip service unless the player in question takes the recommendations to heart.
"It wasn't by snapping our fingers that things were going to get back on track for Joshua," explained Julien. "We wanted to see a progression, and that's exactly what we saw.
"Lots of players show up to my office and ask how they can become a better player. We obviously formulate a plan, but it doesn't always work out. Josh took it very seriously, even throughout the summer, as he'd be in contact with assistant coaches to keep the team abreast of his progression. He arrived at camp with Olympic-level conditioning and a fantastic attitude."
