xGF% is his team's share of 5v5 expected goals while he was on the ice, from our own expected goals model; HDCF% counts only high-danger chances (xG of 0.15 or more). IPP is the share of his team's 5v5 goals while he was on the ice that he scored or assisted on. Relative stats compare him with his team when he was off the ice. Goals above expected and ixG/60 use his own shots at all strengths. PDO and OZS% describe luck and deployment, so their bars are grey.
Play styleOffensive-minded defenseman
Trait percentiles vs. NHL defensemen · 2025-26
Mailloux creates offense through shooting volume and speed, consistently activating with the puck on his stick. His defensive instincts lag behind his offensive tools, and he struggles to generate quality chances or thread passes to teammates.

Where he shoots from
Slot 13% · Mid-range 23% · Perimeter 64%(119 unblocked shots)
Strengths
- Shooting volume ranks 67th percentile, firing often from the point
- Speed in 68th percentile helps him join rushes and escape pressure
- Physicality at 61st percentile gives him presence in battles
Watch-outs
- Defensive impact ranks just 19th percentile, leaving him vulnerable in coverage
- Playmaking at 31st percentile limits his ability to set up teammates
- Puck management at 26th percentile suggests careless decisions with the puck

Game Score gives credit for everything a player does in a game. Goals (1.0) and assists (0.7 primary, 0.5 secondary) count most; shots, blocks, hits, takeaways, penalties drawn, faceoff wins, killing penalties, and holding down the other team's chances add to it. Only mistakes subtract: goals against at 5-on-5, giveaways, penalties taken, faceoff losses, and allowing more chances than an average player would. A player who is there to defend or kill penalties is not marked down for not scoring. Goalies are measured by goals saved above expected.
