Sabres run the Rangers off the ice on the underlying numbers

The verdict · earned

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

BUF 5 · NYR 3
◆ By the ModelJul 12, 10:50 AMxG: 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

Buffalo's 5-3 win understates how thoroughly they dominated. The Sabres controlled 68% of expected goals at 5-on-5 (4.53–2.18), yet got outshot on volume—New York held 43% of shot attempts. The Rangers were dangerous with limited chances, scoring at a clip their underlying numbers can't sustain.

The quality gap was stark. Buffalo generated 0.087 expected goals per shot; New York managed 0.041. That's a 2-to-1 ratio—Buffalo's looks were more than twice as threatening. The Sabres piled up 9 high-danger chances to New York's 3, and when the puck got loose in transition, both teams' rush offense hummed: 3 goals apiece on 20 rush chances. But New York's power play tilted the expected-goals math. On 7 PP shots, they scored twice—0.33 expected goals worth of danger converted at a rate that won't repeat.

Where the score almost ran away with the narrative: New York outperformed expected goals by 0.53 at even strength (Shesterkin: 22/26, 0.846 SV%, +0.53), while Buffalo underperformed by 0.82 (Luukkonen: 17/20, 0.850 SV%, -0.82). Shesterkin made saves. Luukkonen didn't, at least not enough. Buffalo's domination in shot creation—quality, volume per chance, and high-danger conversion—overcame goaltending variance and left New York with no pathway to a second win.

The Sabres' turning point came early in the third: Zach Benson's wrist shot from the slot at 18:45 of P3 shifted the game's trajectory. From that moment, the expected-goals gap was insurmountable.

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 12, 10:47 AMEdited 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 model projects a 2.5–2.5 game with the Rangers at 51% win probability—pick'em territory.

The metrics confirm it. Buffalo and New York share 49.0% Corsi, while the Sabres hold 50.0% in expected goals share to New York's 48.0%—barely perceptible. But Buffalo's 1.020 PDO signals they're outfinishing their underlying play. The Rangers' 1.009 PDO sits closer to sustainable, meaning Buffalo is riding luck that will regress.

The forward matchup tips toward Buffalo.

Jason Zucker leads at 1.07 expected goals per 60 minutes, 14 goals, and 6 high-danger chances. His 15.1% shooting percentage reflects genuine skill. Josh Doan (1.01 xG/60, 15 goals, 11.5% shooting) runs nearly parallel.

New York's response is slighter. Adam Sykora sits at 0.91 xG/60 with 3 goals and zero high-danger chances. He's shooting 20.0%, unsustainably hot. Gabe Perreault's 0.79 xG/60, 8 goals, and 13.1% shooting offer steadier substance but lag behind Buffalo's pair.

Neither team has scored from high-danger chances or rebounds—mutual stalemate in close-quarters ice that neutralizes finishing luck. Buffalo's Jack Quinn and New York's Vincent Iorio are defensive vulnerabilities. In a game without margin, every edge tilts the scales.
