The Sabres are the model's lean over the Blackhawks — with PDO regression in play

Written from the numbers

The read

Edited for clarity
◆ By the ModelOct 3, 9:02 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

Buffalo is the model's clear favorite — a 2.9 to 3.5 projection with the Sabres at 61% win probability. The case is workload, not luck.

The Sabres own the underlying play at 5v5, carrying 48.3% expected goals to Chicago's 33.9%. Territory compounds the gap: Buffalo drives 56.5% of shot attempts while the Blackhawks manage 42.2%, pressing Chicago into a territorial disadvantage the hosts cannot overcome.

Both teams are running cold on conversion. Chicago's PDO of 0.937 sits in regression territory. Buffalo is colder at 0.891 — a clear sign that positive regression waits if the Sabres keep generating looks. This is the edge: Buffalo outworks Chicago, and the score eventually reflects the workload.

The goaltending matchup presents no separation. A. Soderblom arrives at −2.1 expected goals against per game in 1 GP on 81.2% save percentage. U. Luukkonen is marginally worse: −2.2 expected goals against in 1 GP, 77.3% save percentage. This is not where the game is decided.

Discipline at the rims determines the margin. Chicago's sharpest scoring zone is the slot, where they have 4 goals on 29 shots (14%); Buffalo must deny that space. Buffalo's edge is the left circle — 4 goals on 21 shots (19%) — where they own both volume and finish. How Chicago defends the left circle determines whether Buffalo's expected-goals advantage becomes a lopsided scoreline.

The model favors Buffalo because the fundamentals align: territory, volume, and expected production all point the same direction. It is not declaring the Sabres elite — only that they are better than Chicago tonight, and the numbers are coherent enough to trust.

This is a preview, so every number on it is about form and rates — what each club has been doing, not what it will do tonight.

The strip above is the model's lean, built from each side's chance creation and prevention, goaltending, rest and home ice. It is not a betting line and nobody here is telling you to wager on it. Full glossary →

Win prob
How often this matchup ends in a win for that club, over many simulated tries. It is a lean, not a prediction — 60% teams lose plenty.
xGF/60
Expected goals a club creates per sixty minutes of play — its scoring-chance rate, independent of how many games it has played.
xGA/60
The same rate for chances it gives up. Lower is better.
PDO
Shooting % plus save % — a luck gauge that drifts back toward 1.000. Well above it flags a club that has been running hot.
