◆ By the ModelJul 12, 2:46 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 7–4 victory over Toronto tells a story the expected goals didn't: a rout on the scoreboard, a near tie in underlying quality. The Sabres' xG split 3.29–3.33, nearly 50–50, yet they scored seven while the Maple Leafs scored four. The gap was pure variance—Buffalo overperformed their expected goals by 3.67; Toronto overperformed theirs by only 0.71.

Process favored neither team much. The Maple Leafs held 43% of shot attempts (23–31 on goal), traded high-danger chances at 5–4, and scored two goals off 25 rush chances. Their goaltender J. Woll saved 24 of 30 shots but ran 2.67 goals short of expected, suggesting Buffalo's finishing was lethal or lucky, probably both.

Buffalo was more lethal off the rush, scoring five of 31 chances. Their four goals from low-danger areas made the difference. C. Ellis entered in relief and delivered 16 saves on 18 shots with a +0.58 expected performance, while U. Luukkonen's early work proved costly—1.3 goals worse than expected on five shots.

Rasmus Dahlin drove the offense with three goals and two assists. His wrist shot from the top of the circles at 19:16 of the third period proved the turning point. M. Samuelsson distributed three assists in support, while Toronto's A. Matthews posted one goal and two assists despite the loss.

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, 2:44 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 cannot decide. Buffalo projects to 2.6 goals against Toronto's 2.5, with the Sabres at 52% win probability—functionally a pick'em. This is the rare matchup where the betting market gets it right.

The Sabres own the underlying play. At 5v5, they're outgenerating Toronto 50.0% xG to 46.0%, and they're controlling territory at 49.0% Corsi to 45.0%. Buffalo has been the hotter team lately too, running 7-2-1 over their last 10. Toronto is -8 in goal differential over the same stretch, evidence of defensive deterioration more alarming than their record might suggest.

Here's the catch: the Sabres are running unsustainably hot. A 1.020 PDO means they're converting chances at a rate that always regresses. Toronto sits at 1.002, closer to the long-term mean. If Buffalo's shooting luck normalizes, their underlying advantage shrinks.

Buffalo's offense runs through Jason Zucker (1.07 xG/60, 14G 14A, shooting at 15.1%) and Josh Doan (1.01 xG/60, 15G 18A on 11.5%), with Zucker accounting for 6 high-danger goals and Doan for 2. Toronto counters with Auston Matthews at 1.10 xG/60 and 17 goals, though he's converted just once in high-danger situations—a potential sign of variance returning to mean. John Tavares anchors the second line: 0.91 xG/60, 15 goals, 24 assists, 3 of those from high-danger areas.

Neither team generates rebounds at a usable rate (both 0%). Buffalo's defensive weak link is Jack Quinn; Toronto's is Bo Groulx. Both vulnerabilities could matter in a tight game.

The prediction market treats this as essentially even money, and it should. The Sabres have the possession edge and hot streak; Toronto has the secondary scoring depth that can split a goalie's attention. Toronto's recent defensive struggles are concerning enough that the underdog tag is fair, but not by much. The Sabres' PDO spike could evaporate any night.

This is a game that could flip either way on a lucky bounce. Trust the model's 52% read.
