STL 5 · CHI 3
◆ By the ModelJul 12, 11:16 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

St. Louis stole this 5-3 win. Chicago controlled 55% of expected goals (4.04–3.27)—a 13-point margin—and walked away losing. The Blackhawks hit shot attempts 55–45, dominated high-danger chances 8–3, and still couldn't finish.

This was goaltending variance masquerading as strategy. J. Hofer converted a bad situation into elite performance: 31 saves on 34 shots, posting a 0.912 SV% and stopping 1.04 goals above expected. Meanwhile, A. Soderblom couldn't replicate his team's pressure. Twenty-three stops on 28 shots, 0.821 SV%, gave up 1.73 goals above expected—a three-goal swing entirely traceable to the crease.

Chicago's execution crumbled under volume. The Blackhawks scored two goals from low-danger areas (the kind of mistake a starting goaltender shouldn't allow). On the rush, though, they were lethal: three goals on 30 chances. St. Louis countered with five goals on 27 rush chances—marginally more efficient, decisively more ruthless.

Both teams crashed the net effectively, generating five rebound opportunities each. Neither converted. St. Louis's real edge: they outperformed their expected goals by 1.7, suggesting either elite finishing or fortunate bounces. In a 5-3 game decided by variance, it amounted to the same thing.

Ilya Mikheyev's wrist shot from the slot at 13:35 of the third period proved the turning point, though the scoreboard reflected luck more than dominance.

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, 11:13 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 renders this a near-toss: St. Louis projects to 2.6 goals, Chicago to 2.4, with the Blues holding 54% win probability. In a league where two-point spreads are noise, this is the definition of a pick'em.

The difference lies in process. St. Louis owns the underlying play—49.0% expected goals share compared to Chicago's 42.0%—a gap that surfaces in shot quality and possession metrics alike. The Blues' 48.0% Corsi to Chicago's 46.0% confirms they're generating more total shot attempts. Luck has balanced the scales so far: St. Louis sits at a 1.000 PDO, Chicago at 0.996, meaning neither team has been rewarded or punished by the variance that typically distorts single-season results.

The Blues' edge is real but narrow. Jimmy Snuggerud (0.86 xG per 60, 15 goals, 22 assists, 11.9% shooting) and Dylan Holloway (0.82 xG per 60, 13 goals, 24 assists, 10.8% shooting) anchor the attack with consistent offensive pressure. Holloway's higher assist total suggests he works as a creator; Snuggerud's sharper shooting rate—2 high-danger goals on his volume—marks him as a finisher. Neither player has punished Chicago hard enough yet to lock the game away before puck drop.

Chicago counters with Tyler Bertuzzi, whose 7 high-danger goals lead the forward group and hint at closer finishing before the bar closes. His 0.85 xG per 60 sits nearly flush with Snuggerud's, but at 20 goals and an 18.0% shooting rate, Bertuzzi has converted chances at a rate that defies the underlying metrics. Connor Bedard's 0.82 xG per 60 and 27 assists suggest a facilitator role, though his 17 goals and 11.8% shooting mark him as a genuine two-way contributor rather than a pure setup man.

The tactical picture reinforces the evenness: both teams sit at 0% high-danger goal rates and 0% rebound goal rates—a curiosity that suggests neither has locked into a reliable scoring recipe. St. Louis's defensive weak link is Snuggerud, while Anton Frondell carries that burden in Chicago. These vulnerabilities will invite late-game chaos if the score remains close.

St. Louis should win based on process. The 54% line respects that edge without overplaying it.
