Predators steal one from the Mammoth against the run of play

The verdict · stolen

The Predators stole one. They lost the expected-goals battle 2.81–4.50 and won anyway.

NSH 4 · UTA 3
◆ By the ModelJul 11, 10:19 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's 4-3 win is a heist. The Mammoth controlled 62% of expected goals at 4.50–2.81 — one of the clearest mismatches between quality and result.

Utah dominated the board. The Mammoth held 54% of shot attempts (31–26 on goal) and created eight high-danger chances to Nashville's five. Yet they scored three times on 4.50 xG, leaving 1.50 goals in the rink.

J. Saros stole the game. The Predators goaltender stopped 28 of 31 (0.903 SV%), finishing 1.50 goals above expected. V. Vanecek allowed 1.19 goals beyond expectation on 22 of 26 attempts (0.846 SV%) — the margin.

Steven Stamkos's wrist shot from the slot at 13:17 of the third period was the turning point. Nashville converted 40% of high-danger chances (2 of 5), crashing the net effectively and capitalizing on four rebound opportunities (one converted). Utah found efficiency only off the rush — 2 goals on 34 attempts — and wasted their other premium opportunities.

Everything else belonged to Nashville: slot discipline, rebound access, goaltending, the scoreboard.

This lingers. Utah earned the win based on volume, shot quality, and workload. Saros and variance overruled it.

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, 10:18 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

Utah enters favored, with the model giving the Mammoth a 55% win probability in a projected 2.4–2.7 goal game. The advantage flows from superior shot quality: Utah generates 52.0% of expected goals at 5v5—an edge that compounds in close, low-scoring contests. The Mammoth also control possession, maintaining 53.0% Corsi, which forces Nashville into a reactive posture.

Rest magnifies the tilt. The Predators play on 1 day of rest while the Mammoth arrive on 5 days—a gap that favors the rested team in tight games. Add J. Saros on a back-to-back: the Predators likely start a backup or an overworked starter.

Both teams have recorded 0% high-danger goal conversion and 0% rebound scoring. Defensively, Jonathan Marchessault is Nashville's obvious weak link. Maveric Lamoureux represents Utah's equivalent liability.
