Penguins run the Red Wings off the ice on the underlying numbers

The Penguins earned it — the game and the expected-goals battle both.

◆ By the ModelJul 11, 10:52 PMxG: xgboost-0.758Edited for clarityDrafted from NHL play-by-play by Backcheck's model, worded for clarity by an AI editor that may not change a number. Nobody at Backcheck was at the rink. How this works

The Penguins demolished the Red Wings 4-1, and the underlying numbers backed the margin — except for one detail. Pittsburgh controlled 67% of expected goals at 5v5 (3.91–1.95), a gap that typically demands a wider scoreline. J. Gibson saved 1.91 goals above expected, a stark overperformance that made an overwhelming advantage look merely decisive.

Detroit's collapse started with volume. The Red Wings managed just 12 shot attempts to Pittsburgh's 31, generating 1.95 xG — and then underperformed even that. High-danger chances went 3–6 to Pittsburgh. The Penguins' shot quality was superior: 0.069 xG per shot versus Detroit's 0.047. Every opportunity cut deeper.

Pittsburgh was efficient in transition, scoring three goals on 29 rush chances. Two came from low-danger areas, the sort of margins that emerge when a team controls the game this thoroughly. S. Skinner stopped 11 of 12 with a 0.917 save percentage and a +0.95 differential, solid work against manageable volume.

The stat that matters most is Gibson's. He saved 1.91 goals beyond expectation and lost by three. That's the measure of Pittsburgh's dominance.

New to these numbers?

Two things happened in this game: who created the better chances, and who put the puck in the net. They are not the same thing, and this page separates them on purpose.

The one to watch is expected goals— the best single read on who deserved to win. When it disagrees with the scoreboard, that disagreement is usually the story. Nothing here is a projection; every figure is computed from this game's play-by-play. Full glossary →

xG
Expected goals. Every shot scored by how often that exact look goes in. 2.5 xG means the chances were worth about two and a half goals.
HD
High-danger chances — shots from the slot and the crease, where shots actually become goals.
Corsi
Every shot attempt, including the ones that missed or got blocked. A rough read on who had the puck.
Adj.
Score-adjusted. Teams that trail shoot more and teams that lead sit back, so this corrects the attempt count for the scoreboard.
GSAx
Goals saved above expected. A positive number means the goalie stopped more than an average goalie would have on those shots.
PDO
Shooting % plus save % — a luck gauge. It sits near 1.000 over a season, so a game far from it usually means the bounces decided it.

The read

Edited for clarity
◆ By the ModelJul 11, 11:02 PMEdited for clarityDrafted from NHL play-by-play by Backcheck's model, worded for clarity by an AI editor that may not change a number. Nobody at Backcheck was at the rink. How this works

Pittsburgh and Detroit project to a 2.6-2.6 tie, the Red Wings at 50% win probability. You cannot separate them.

The season 5v5 numbers explain why. Pittsburgh leads in xG% (51.0% to 49.0%) and Corsi% (50.0% to 49.0%), but both edges are negligible. The PDO gap is more telling: Pittsburgh's 1.012 reflects efficiency running above expected; Detroit's 0.985 is below. The models still call it even.

Form has shifted recently. Detroit are 7-2-1 in their last 10 games; Pittsburgh are -5 in goal differential over the same span. The underlying 5v5 numbers have not moved in kind.

Both C. Talbot and A. Silovs are on back-to-backs. A tired starter or a backup will change the matchup at the margins.

Filip Hallander (1.28 xG/60) is likely out for further evaluation. Rickard Rakell (1.01 xG/60, 13G, 3 HD goals, 12.1% shooting) is Pittsburgh's forward to watch. His shooting rate is running elevated. Detroit's key forwards are Alex DeBrincat (17G, 0.88 xG/60, 2 HD goals, 9.0% shooting) and Marco Kasper (7G, 0.81 xG/60, 1 HD goal, 6.1% shooting). DeBrincat's 9.0% is more sustainable than Kasper's 6.1%.

Both teams shoot 0% on high-danger and rebound chances—statistical anomalies that will normalize. Caleb Jones is Pittsburgh's defensive liability; Axel Sandin-Pellikka is Detroit's. Whichever stays fresher and benefits from shooting regression wins.
