The Bruins stole one. They lost the expected-goals battle 3.71–2.79 and won anyway.

◆ By the ModelJul 12, 2:44 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

The Bruins stole this game. Despite losing the expected-goals battle 2.79–3.71 (43–57%), Boston won 3-2 in overtime — a heist that hinged on J. Swayman's plus-1.71 SV% and a tip-in from D. Pastrnak at 00:15 of overtime.

Nashville outplayed Boston at even strength, controlling 57% of expected goals at 5v5. The Bruins held just 48% of shot attempts (28–30) but won the high-danger chances 6–4. Goaltending was the difference: J. Swayman posted 0.933 SV%, stopping 1.7 goals above expected, while J. Saros delivered 0.893 SV% on 25/28 saves.

Both teams struck on the rush. Boston scored 2 goals on 25 rush chances; Nashville scored 2 on 31. Neither team capitalized on rebound opportunities — Boston created three, Nashville eight, each converting zero. Nashville underperformed their xG by 1.71 goals, wasted quality that should have buried Boston. Swayman's dominance prevented the blowout and sent the game to overtime.

D. Pastrnak ended it from the doorstep, securing the two points on a night where the Bruins' superior finishing and goaltending overcame Nashville's control of play.

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, 2:43 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 won't pick a side: 2.6 expected goals apiece, 51% win probability for Boston.

Boston is 8-2-0 over their last 10 games; Nashville sits at -8 goal differential over the same span. The divergence looks damning, but the underlying 5v5 metrics tell a different story. Nashville owns a shot-quality edge at 49.0% xG% and 50.0% Corsi%, better than Boston's 47.0% xG% and 49.0% Corsi%. The problem for the Predators isn't generation—it's finishing. Both teams score on 0% of their high-danger chances and fail to convert rebound opportunities, suggesting neither has rhythm in scoring areas.

The variance in results comes down to shooting luck. Boston's 1.023 PDO means the Bruins convert at an inflated rate and allow fewer goals than their shot volume predicts. Regression is inevitable. Nashville runs 0.992, suggesting their results are roughly tracking their underlying shot volume.

Individual performance matters at this margin. Nashville's Zachary L'Heureux generates 0.85 expected goals per 60 minutes with 4 goals and a 16.0% shooting rate—both signs of unsustainability. Filip Forsberg offers more durable production: 0.80 xG/60, 23 goals, 13.6% shooting. Boston counters with Viktor Arvidsson's elite 1.04 xG/60 and 18 goals at 13.0%, and Tanner Jeannot's 0.75 xG/60 with 6 goals at 8.3% shooting. Jeannot's rate suggests that 6 won't hold.

Defensively, Jonathan Marchessault is Nashville's weak link; Elias Lindholm carries that role for Boston. In a game this close, those vulnerabilities are worth hunting.

Boston's recent form is real, but it's built on a PDO that won't persist. Nashville's shot quality is real, but it hasn't translated to goals yet. The team that regresses slower wins.
