◆ By the ModelJul 12, 4:49 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

New Jersey's 3-1 win masks a dominant performance: the Devils controlled 69% of 5v5 expected goals (4.96–2.22) and generated far cleaner scoring chances. The Blues' shots came from bad angles—they held 44% of attempts but managed just 0.042 expected goals per shot, compared to New Jersey's 0.083.

Goaltending papered over the gap. J. Binnington kept St. Louis within striking distance despite facing a 3-to-1 quality disadvantage, posting a +2.96 save percentage above expected. J. Markstrom (NJD) played well with a +1.22 performance, but the Devils squandered their advantage: they underperformed their xG by 1.96 goals while the Blues underperformed theirs by 1.22. When a team generates superior looks and still misses them, volume compensates—the Devils' 3 goals on 30 rush chances proved it.

Nico Hischier's wrist shot from the high slot in the third period (19:55) sealed the Devils' grip on the game. New Jersey sustained pressure with 5 rebound opportunities (converting zero) and a 69% expected-goal share—the opposite of a squeezed-out victory. They overwhelmed St. Louis structurally, then converted it.

The final shot count (26–33) tells the true story: St. Louis never generated the dangerous looks required to match a team playing suffocating defense. The expected-goal split (2.22–4.96) explains why.

    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, 4:59 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 2.4 to 2.5 expected goals and tags the Blues at 52% win probability. This is a genuine pick'em.

    Both teams are limping into this game. The Blues carry a minus-9 goal differential over their last 10 games; the Devils are worse at minus-12. Form has abandoned both.

    But season 5v5 metrics tell a different story. The Devils have controlled play all year—51.0% Corsi, 50.0% expected goals—while the Blues lag at 48.0% Corsi and 49.0% xG%. The Devils should have been winning more often. That they haven't suggests a PDO problem: New Jersey is running at 0.971, well below normal, while St. Louis sits at a perfect 1.000. The Devils are due for positive regression; the Blues are living dangerously hot.

    Goaltending adds complexity. Both J. Markstrom and J. Hofer are on back-to-backs, raising the backup-start possibility for either side. Fatigue matters in a game this tight.

    The Devils' offense runs through Timo Meier, who's generating 1.08 expected goals per 60 minutes with 13 goals, 3 high-danger opportunities, and a 6.7% shooting rate. Jack Hughes provides secondary production at 0.88 xG/60 with 18 goals and an 11.5% shooting rate that suggests sustainable finishing.

    The Blues counter with Jimmy Snuggerud (0.86 xG/60, 15G 22A, 2 high-danger goals, 11.9% shooting) and Dylan Holloway (0.82 xG/60, 13G 24A, 1 high-danger goal, 10.8% shooting).

    Johnathan Kovacevic is the Devils' defensive weak link; the Blues can hunt him in transition. St. Louis must contain Meier, whose elite shot quality and 13 goals make him the game's most dangerous player.

    One curiosity: both teams are generating 0% high-danger goals and 0% rebound goals relative to attempts. That flat conversion profile means the margin will likely come from territorial control and fatigue, not secondary scoring.

    Neither team looks especially sharp. The Devils' territorial advantage across Corsi and xG% suggests they should be favored, but their recent form collapse and St. Louis's lucky finish rate create genuine uncertainty. That 52% for the Blues doesn't feel speculative—it feels earned.
