Islanders pull away from the Avalanche

The verdict · earned

The Islanders earned it — the game and the expected-goals battle both.

COL 3 · NYI 6
◆ By the ModelJul 11, 6:56 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

High-danger chances split 8-8 in a 6-3 Islanders win—a complete tie in the most dangerous areas, yet the Islanders pulled away by three. That efficiency came from two sources: shot quality and goaltending.

The Islanders generated 0.076 expected goals per shot versus Colorado's 0.058, a quality edge that mattered more than volume. On the rush, where both teams had 26 chances, the Islanders scored three to Colorado's two. NYI converted 2 of 8 rebound opportunities; Colorado converted zero.

I. Sorokin (NYI) made 35 saves on 38 shots (0.921 SV%), finishing 1.26 goals above expected. M. Blackwood (COL) saved 36 of 41 (0.878 SV%), a gap in performance that decided the game.

The underlying expected goals split 4.94–4.26 in NYI's favor, a modest edge for a three-goal margin. The story isn't that one team outplayed the other—it's that the Islanders made their few advantages count where it mattered: shot quality, rush conversions, and goaltending.

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, 6:53 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

Colorado's projection holds firm: 2.9 goals to 2.5, with a 56% win probability edge. The Avalanche have earned it on form, not luck alone.

The form is obvious. Colorado has run 9-0-1 over their last 10, stacking recent wins into an edge New York hasn't built.

The underlying play reinforces the projection. Colorado dominates at 5v5, generating 57.0% of expected goals while allowing 48.0%, and they control territory at 57.0% in Corsi—a territorial tilt that puts the Islanders on their heels. This is the core edge.

But here's the drag on confidence: Colorado's PDO sits at 1.021, running hot. The Islanders are cooler at 0.993. Regression will come for both, and when it does, the gap narrows. Factor in variance, and that 56% conviction softens.

The goaltending setup is murky. I. Sorokin faces a back-to-back, as does S. Wedgewood. Both could see backup time or tired starters—a wild card that cuts both directions.

The matchup details add texture. Colorado leans on Artturi Lehkonen at 1.11 xG/60 with 18G and 22A, shooting at 14.9%, and Ross Colton at 1.10 xG/60 with 7G and 15A at just 4.9%—a shooter waiting to heat up. New York counters with Anders Lee at 1.20 xG/60 (9G, 20A) and Bo Horvat at 0.87 xG/60 (18G, 10A, 12.8% shooting). Lee's per-60 threat is sharp; Horvat's volume offsets his efficiency gap.

The defensive vulnerabilities cut both ways. Colorado must account for Nazem Kadri's exposure; New York has Alexander Romanov as a weak link. These aren't hidden—both teams know who to target.

Take Colorado at 56%. The model's lean holds on pure play, even with PDO regression factored in. The Avalanche own the territorial battle badly enough that mean reversion in luck closes but doesn't flip the edge. The form, combined with underlying control, is too much for a team running cooler on both luck and efficiency.
