St. Louis stole this one. Calgary controlled the underlying metrics—expected goals 3.91 to 3.30, shot attempts at 51% of the total—yet lost 4–2. The difference: goaltending gulf and finish variance.

J. Hofer turned in the performance that decided the night. He saved 1.91 goals above expected, posting a 0.931 save percentage on 29 shots. D. Wolf, his counterpart, surrendered 0.70 more goals than anticipated, finishing at 0.857. Hofer's margin and Wolf's underperformance account for nearly the entire 2-goal final gap.

Calgary squandered 1.91 goals' worth of expected performance. They generated 5 high-danger chances and converted none. The Flames were efficient on the rush—2 goals on 32 chances—but their offense couldn't capitalize elsewhere. They crashed the net effectively, creating 3 rebound opportunities with no payoff.

St. Louis was nearly as profligate: 0 for 6 on high-danger chances. Yet they found their efficiency through the same rush game, scoring twice on 19 chances, a conversion rate that punished Calgary's mistakes. Pius Suter's tip-in from the slot (P3, 13:33) was the turning point.

The Flames will rue this as a squandered advantage in play quality. Calgary dominated possession and shot attempts, controlled the expected-goals share, and still left with nothing. For St. Louis, goaltending and opportunism conquered better process—exactly the recipe for stealing a game that the underlying numbers say should've gone the other way.

The model projects St. Louis and Calgary as dead even—2.5 goals each, with Calgary at 50% win probability. This is as close to a pick'em as exists.

The underlying metrics offer no clarity. St. Louis leads in expected goals at 5v5 (49.0% xG%), while Calgary edges it in possession (49.0% Corsi%). St. Louis sits at a perfect 1.000 PDO; Calgary's 0.985 shows a team on the wrong side of variance.

Calgary's real problem is recent form. Over the last ten games, the Flames are -13 in goal differential—a dragging anchor that masks their underlying competitiveness. That negative PDO, though, cuts both ways: it suggests regression is coming, just not guaranteed to arrive Sunday.

Back-to-back situations could tilt the game. D. Wolf for Calgary and J. Binnington for St. Louis are both at risk of either backup duty or shortened minutes. Fatigue compounds goaltending inconsistency; monitor starting lineups closely.

St. Louis's Jimmy Snuggerud (0.86 xG/60, 15G) and Dylan Holloway (0.82 xG/60, 13G) drive play. Calgary counters with Blake Coleman (0.89 xG/60, 16G, 11.4% shooting) and Matt Coronato (0.80 xG/60, 10G, 6.6% shooting). Coleman's underlying rate edges Snuggerud's; Coronato's 6.6% shooting is an outlier.

This is a game where recent outcomes (Calgary's -13 slide) and underlying talent (roughly even) point in opposite directions. Until the Flames stabilize their execution, St. Louis enters with the slightest of edges.

Three Things to Watch

• Starting goaltenders — both on back-to-backs, both vulnerable to rest decisions
• Calgary's expected-goals profile versus its streak — does the team finally see positive regression, or does bad luck extend?
• Coleman versus Snuggerud in primary scoring matchup — whichever gets clearer looks likely settles it
