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.

Trait percentiles vs. NHL centers · 2025-26
Mittelstadt is a pass-first creator who generates chances through skilled linemate setup rather than shot generation. He struggles with defensive responsibility and physical engagement, limiting his overall impact at five-on-five.

Where he shoots from
Slot 46% · Mid-range 38% · Perimeter 16%(135 unblocked shots)
Strengths
- Strong playmaking ability puts him in the 77th percentile for creating chances
- Slot-heavy shot profile concentrates his limited 135 unblocked shots where they matter most
- Adequate rush chance creation at 56th percentile keeps play moving up ice
Watch-outs
- Bottom 5th percentile in puck management leads to turnovers and breakdowns
- Minimal physicality at 5th percentile means he avoids engagement in loose pucks
- Forechecking in just 14th percentile leaves defensive assignments unfinished

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.
