◆ By the ModelJul 11, 6:42 PMxG: 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

Nashville took the Flames 5-1 despite firing shot attempts dead even at 28 apiece—the most striking disconnect between corsi and score. Where the dominance showed up: expected goals (3.32–2.59 in NSH's favor) and dangerous chances. The Predators converted 3 of 5 high-danger opportunities; Calgary mustered only one in that zone. On the rush, Nashville buried 5 goals from 28 chances.

J. Saros played a near-perfect game, stopping 27 of 28 with a 0.964 save percentage and 1.59 goals above expected. Calgary's goaltending did not hold. D. Cooley saved only 12 of 16 (0.750 SV%), surrendering 2.10 goals above expected in a short outing. D. Wolf took over and posted a 0.917 mark, saving 2.3 goals above expected, but the game was already out of reach.

The variance cut sharply both ways. Nashville overperformed their expected goals by 1.68, either from elite finishing or bounces going their way. Calgary underperformed by 1.59—they created quality chances, including three rebound opportunities, but converted none.

Morgan Frost's snap shot from the slot (13:39, third period) marked the turning point.

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, 6:40 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 model projects a 2.5–2.7 goal game with Nashville at 54% win probability—about as close to a pick'em as you'll find. This matchup hinges on whether Calgary's recent surge holds or whether Nashville's underlying metrics finally convert.

Calgary enters hotter, posting a 5-3-2 record over their last 10 games. Nashville hasn't. They're -16 in goal differential over the same span, a deficit large enough to undermine their shot-generation advantage. The Predators lead at even strength with 49.0% expected goals and 50.0% Corsi, while the Flames sit at 47.0% xG and 49.0% Corsi.

The underlying edge belongs to Nashville. But Calgary has luck working in its favor. At 0.985, the Flames' PDO is running cold—a condition that doesn't last. Positive regression is coming, and it could arrive exactly when it matters.

Blake Coleman drives Calgary's offense, generating 0.89 expected goals per 60 minutes with 16 goals and 12 assists, including 2 high-danger chances. His 11.4% shooting rate indicates that process and results are aligned, not that he's overperforming. Matt Coronato adds complementary scoring: 0.80 xG/60 with 10 goals and 16 assists, though his 6.6% conversion suggests room to regress downward.

For Nashville, Filip Forsberg and Zachary L'Heureux embody the process-versus-results divide. Forsberg leads with 23 goals and 17 assists while maintaining 0.80 xG/60 and shooting at 13.6%—he's found the high-danger area 4 times. L'Heureux presents the inverse: 0.85 xG/60, only 4 goals, and 1 high-danger finish, despite shooting at 16.0% when he does attempt shots.

Nashville's metrics forecast a tight offensive game. Calgary's luck—and recent form—suggest tight results. Defensively, Calgary can target Coronato's weaknesses, while Nashville will probe Jonathan Marchessault, though neither edge is decisive.

In a game without decisive underlying separation, recent form barely tilts Calgary. But 54% for a team posting better 5v5 numbers isn't a surprise. This truly is a coin flip.
