The verdict · stolen

The Blues stole one. They lost the expected-goals battle 2.90–3.38 and won anyway.

STL 4 · DAL 0
◆ By the ModelOct 3, 12:03 AMxG: xgboost-0.765Edited 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

St. Louis shut out Dallas, 4-0, with J. Hofer playing the game of his life in goal. The Blues were relentless off the rush. Dallas created scoring chances but never finished.

The offensive workload told a different tale. Dallas controlled play with 51% of shot attempts and led in expected goals, 3.38–2.90, yet left empty-handed. The Stars underperformed their workload by 3.38 goals—a gulf between process and result. St. Louis overperformed by 1.10.

Hofer stole the evening. The Blues goaltender posted 25 saves on 25 shots while facing 3.38 expected goals and allowing zero—a performance 3.38 goals better than predicted. St. Louis and Dallas created the same high-danger chances (4–4), but only the Blues finished. J. Oettinger faced 2.90 expected goals but allowed four, and that gap decided the game.

M. McTavish opened from 11 feet off a rebound—a 14% chance—just 3 seconds after C. Parayko's shot from the point. D. Dvorsky added the second from 23 feet off the rush, a 19% chance. Two empty-netters—J. Snuggerud from 64 feet, P. Suter from 58 feet, both 14% chances—sealed the shutout.

Special teams misfired for both (F for both). St. Louis was undisciplined; Dallas was not. The biggest transition concern: 32 rush shots worth 2.81 expected goals allowed, yet Dallas converted none.

The goals

  • STL 1–0, 01:34 of the first. M. McTavish, snap shot from 11 feet, a 14% chance by the model (a rebound), past J. Oettinger. Assists: C. Parayko, J. Snuggerud. 3 seconds after a STL shot by C. Parayko. Win probability moved 14 points.
  • STL 2–0, 13:05 of the second. D. Dvorsky, snap shot from 23 feet, a 19% chance by the model (off the rush), past J. Oettinger. Assists: P. Broberg, P. Suter. Win probability moved 16 points.
  • STL 3–0, 17:37 of the third into an empty net. J. Snuggerud, wrist shot from 64 feet, a 14% chance by the model.
  • STL 4–0, 17:52 of the third into an empty net. P. Suter, wrist shot from 58 feet, a 14% chance by the model. Assists: C. McMichael, J. Hofer.

What the numbers can't tell you. Whether the finishing was luck or skill, why the benches were run the way they were, who was hurt, and anything said in the room. That is the beat's story, and it is worth reading.

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 ModelOct 2, 12:09 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

Dallas is favored by a narrow margin in a game between evenly matched teams. The model projects a 2.8–3.2 outcome with the Stars at 56% win probability—a lead so thin it's barely an advantage.

Goaltending will decide this. When two teams are this close across all measurable categories, the play between the pipes determines who wins.

The Stars' most productive scoring zone over their last five games has been the point. Dallas has scored 3 goals on 15 shots from the perimeter (20%), a rate that shows their primary threat. St. Louis must deny that lane; allowing the Stars to work freely from the point is an easy way to fall behind.
