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 styleHigh-volume shooter
Trait percentiles vs. NHL wingers · 2025-26
Peterka is a speedster who beats defenders to loose pucks and creates chances through aggressive shooting and smart positioning. He struggles with physical play and transitional puck management, making him less effective in grinding situations.

Where he shoots from
Slot 37% · Mid-range 48% · Perimeter 15%(241 unblocked shots)
Strengths
- Elite speed (81st percentile) allows him to generate rush chances consistently
- Above-average shooting volume (63rd percentile) with smart shot selection near the net (37% slot)
- Strong zone entries (70th percentile) as a speed-based threat in transition
Watch-outs
- Minimal forechecking impact (3rd percentile) limits his value in puck recovery
- Poor puck management (9th percentile) creates turnovers in transition
- Below-average playmaking (41st percentile) makes him less dangerous as a distributor

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.
