The Avalanche stole one. They lost the expected-goals battle 3.36–4.53 and won anyway.

◆ By the ModelJul 12, 4:25 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

Utah dominated expected goals at 57%, but Colorado won 4-2 anyway—this was a theft.

The Mammoth controlled 30 shot attempts to 26, and the xG model gave them 4.53 to Colorado's 3.36. High-danger chances favored Utah 7-5. By every underlying metric, they should have won. They didn't, because S. Wedgewood was immovable.

Wedgewood stopped 28 of 30 shots (0.933 save percentage) and finished 2.53 goals above expected—a performance that rarely happens. He faced seven high-danger chances and turned away all seven. K. Vejmelka, on the other end, let in 0.64 more goals than his xG model predicted. That swing, 2.53 goals each direction, decided the game.

Utah's execution in high-danger areas collapsed. They went 0 for 7 on their clearest looks. Colorado, by contrast, was clinical in transition: they scored four goals on just 20 rush chances, a rate Utah couldn't match at 2 on 27. Martin Necas's slap shot from the top of the circles (second period, 17:17) marked the inflection point—the moment where underlying dominance couldn't stop the scoreboard.

The Mammoth earned this loss through possession and positioning. They created more rebounds, maintained better control, sustained pressure. But generating chances without converting them is just a prettier way to lose. This is precisely the game where one goalie steals a win that expected goals promised to someone else.

      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, 4:25 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

      Colorado owns the underlying play—57.0% xG% and 57.0% Corsi%—but Utah has earned recent form at 7-3-0 over their last 10, while the Avalanche sit at -5 goal differential in the same span. The model projects a 2.7-2.6 edge to Denver at 52% win probability. This is as close to a pick'em as you'll find.

      The concern for Colorado is regression. Their PDO of 1.021 means they're running hot on conversion; Utah's 1.003 suggests they're performing to expectation. That 57.0% Corsi% edge shows the Avalanche drive territorial tilt, but dominance in volume doesn't guarantee wins when you're overperforming on finish.

      Artturi Lehkonen generates 1.11 xG per 60 minutes with 18 goals and 22 assists at 14.9% shooting—elite and sustainable. Ross Colton (1.10 xG/60, 7 goals, 15 assists) carries a 4.9% shooting rate that will improve. Utah counters with Dylan Guenther at 1.02 xG/60 and 28 goals with 15 assists, while Daniil But (1.01 xG/60, 2 goals, 2 assists) has yet to translate volume into output.

      Neither team generates high-danger or rebound goals at meaningful rates—both show 0% in those categories. The scoring will come from the volume and quality of looks, where Colorado has the advantage. Nazem Kadri is Denver's defensive liability; Maveric Lamoureux is Utah's. In a game decided by single goals, that matters.

      Colorado should win this based on underlying metrics, but Utah's recent form legitimizes their presence. The Avalanche aren't a lock.
