St. Louis' 3–2 win was no coup—the expected goals split of 3.50–3.42 suggests a close game played roughly to form. But look closer and the Blues' superiority emerges in the details.

The Blues held 44% of shot attempts (31–40 on goal), generating 0.073 expected goals per shot attempt to Calgary's 0.048. That gap in shot quality haunted the Flames all night. St. Louis converted twice from 28 rush attempts, turning efficiency into victory.

Calgary's underlying metrics told a grimmer story: the Flames scored twice from low-danger areas—the sort of goals a good goalie stops—while underperforming their expected total by 1.42 goals. J. Binnington, St. Louis' goaltender, stopped 1.4 goals above expected. That dominant performance erased Calgary's margin for error.

The Flames created four rebound opportunities but converted none. Rasmus Andersson's wrist shot from the point (14:29, P2) was the game's turning point, but even an industrious Andersson (25:12 on ice, one goal) could not drag his team back.

    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 11, 3:33 PMEdited 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 models project a 2.4–2.6 goal game with the Blues favored at 54% win probability—about as close to even odds as you'll find.

    St. Louis owns the shot edge: 49.0% expected goal share to Calgary's 47.0% at 5v5. Yet the Blues are underwater at -15 goal differential over their last 10, a gap suggesting recent results have lagged underlying talent. Calgary is running cold—the Flames' PDO sits at 0.985, well below the 1.000 long-run mean—positioning them for positive regression. St. Louis is at 1.000 exactly, break-even luck, which means what they've shown is what they'll likely sustain.

    D. Cooley is on a back-to-back. Whether the Blues deploy their backup or ask a tired starter to push will shape the game's tempo.

    Blake Coleman is Calgary's engine. He carries 0.89 expected goals per 60 minutes with 16 goals and 12 assists at an 11.4% shooting rate, plus 2 high-danger goals. That combination—elite chance creation and strong finishing—marks him as a genuine threat. Matt Coronato offers secondary depth, though at 0.80 xG/60, 10 goals, 16 assists, and 6.6% shooting, he's been snakebitten.

    St. Louis counters with Jimmy Snuggerud: 0.86 xG/60, 15 goals, 22 assists, 11.9% shooting, and 2 high-danger goals. His profile mirrors Coleman's nearly exactly. Dylan Holloway (0.82 xG/60, 13 goals, 24 assists, 1 high-danger goal, 10.8% shooting) runs a high-volume role alongside him.

    Both teams have yet to allow a high-danger or rebound goal—either disciplined defense or unsustainable luck. For Calgary, Matt Coronato is the defensive weak link; for St. Louis, it's Snuggerud. The model is right: this is a genuine coin flip. Calgary's cold streak is primed to reverse, but St. Louis holds the structural advantage. Either outcome is defensible.
