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 styleTenacious two-way center
Trait percentiles vs. NHL centers · 2025-26
Kastelic is a high-contact, hard-working forward who excels at puck management and relentless forechecking to create turnovers. His playmaking lags behind his peers, making him more of a complementary piece who generates chances through effort rather than skill.

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.
