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.

  • Playmaking in the 77th percentile drives offensive chances through passes
  • Shooting volume in the 65th percentile reflects aggressive offensive participation

Watch-outs

  • Puck management at just 6th percentile suggests turnovers in possession shifts
  • Physicality at 37th percentile means minimal engagement in board battles
  • Defensive impact at 51st percentile shows middling effectiveness in his own zone

Similar style: Oliver Ekman-Larsson (TOR), Mattias Ekholm (EDM)

Goalies are measured by goals saved above expected.
