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

◆ By the ModelJul 12, 10:00 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

Tampa Bay's 6–3 victory masked a more decisive edge: the Lightning controlled 70 percent of expected goals despite holding only 58 percent of shot attempts (4.85 to 2.08 xG; 33 to 24 on goal). Shot quality—not volume—carried the game.

Pittsburgh generated higher-quality chances relative to their shot volume; the Lightning generated far more dangerous ones. Tampa Bay produced 0.072 expected goals per shot; Pittsburgh 0.045. The gap compounded: the Lightning buried 50 percent of their high-danger chances (3 of 6) and were lethal on the rush, scoring twice on 25 chances. Pittsburgh, by contrast, converted three rush chances on just 21 attempts—a stunning efficiency that went for naught.

Variance cut both ways, but inconsistently. The Lightning overperformed their model by 1.15 goals; Pittsburgh exceeded theirs by 0.92. A. Vasilevskiy (0.875 SV%) beat his xG assumptions (−0.92). S. Skinner underperformed his.

The Penguins' most dangerous moment came early: Egor Chinakhov's snap shot from the top of the circles in the third period (19:58) briefly tightened a blowout. It proved a speed bump.

Tampa Bay's dominance lived in deeper measures: 7 rebound opportunities (2 converted) and clinical execution when it mattered. Off the transition, they were uncatchable.

Pittsburgh played a respectable road game by efficiency metrics—more dangerous looks, proportionally, than their shot count revealed—but they couldn't overcome a Lightning team that turned possession into danger and danger into goals.

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, 9:54 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 pregame model projects PIT 2.5–2.7, with Tampa Bay at 55% to win. That's as close to pick'em as the numbers get.

Tampa owns the underlying play. The Lightning generate 54.0% of 5v5 expected goals versus Pittsburgh's 51.0%, and their Corsi mark sits at 53.0% to Pittsburgh's 50.0%. Yet the model grants Tampa barely more than even odds.

The Lightning's 1.019 PDO signals they're running hot—expect regression. Pittsburgh's 1.012 sits closer to neutral.

Rickard Rakell anchors Pittsburgh's attack. He has 13 goals on 12.1% shooting while generating 1.01 xG/60. Filip Hallander, who produced 1.28 xG/60, is on injured reserve for evaluation and unavailable.

Tampa's scoring spreads across Brandon Hagel and Anthony Cirelli. Hagel carries 23 goals and 1.10 xG/60 at 15.8% shooting. Cirelli has 15 goals with 17.0% shooting and 0.95 xG/60.

At 5v5, neither team has recorded a high-danger goal or rebound goal. Caleb Jones is Pittsburgh's defensive liability; Victor Hedman is Tampa's.

The Lightning's possession and shot advantage merits the favorite's line, but narrowly. When two teams this close collide, the model's coin-flip assessment is the only honest call.
