BUF 2 – 3 BOS

Shot attempts include missed and blocked shots. Expected goals (xG) weigh each unblocked shot by its chance of going in; high-danger is 0.12 xG or more. Power-play goals and chances are the NHL's line, which counts a double minor as two chances and a 5-on-3 from two penalties as two, so the count can run above the number of penalties in the Full Game Log below. Score-adjusted is the share as if the game were tied at a neutral site. Best line and pair: among units with a winning 5-on-5 xG share, at least 2:00 together (4:00 for a pair) and 0.25 xG in those minutes (half that where a goal was scored in them), one that came out ahead on the goals scored and allowed with it out ranks first; the rest is the best mix of that share and those goals, weighted two to one.

Score-adjusted weights each attempt by how often teams take one in that score state, home or away, at that point of the game, league-wide (2016-17 to 2025-26): the share as if the game were tied at a neutral site. Score-tied counts only attempts while tied, and needs 15 tied minutes and 30 attempts.

Each team is expected to score at the league rate for the season, tilted for home ice and scaled for the strength state. The chance Buffalo ends regulation ahead follows from the score and the time left, with a tie going to 3-on-3 overtime and a shootout. The opening value comes from both teams' goals for and against to that date, regressed toward the league average early in a season, plus home ice.

Pinned. A team is pinned when 3 or more of its skaters on the ice are past a minute of unbroken play, at 5v5. A hemmed-in shift is an even-strength shift in which the unit was on for more than 1:00 without a whistle to change on, and stayed at even strength for most of it. A stoppage inside a shift starts the clock over, however it began: what counts is the run of play they could not get off the ice for. Only the time past the minute counts: the first minute of those shifts plays like any other stretch of the game, while past it the play tilts hard toward the end the pinned team is defending (in 2020–21, a pinned team took 28% of the shot attempts; pinned time was 2.4% of all 5v5 play). Pinned time is seconds on the clock, not each skater's seconds added up.

Short rest. An even-strength shift a skater started after less than 45 seconds on the bench, same period only (an intermission is a full rest).

Tired legs. Every shot attempt is tagged by how far into their shifts the defending skaters were, on average, at that moment (goalies left out). The row is the share of xG against that came with them 40 seconds or more in. xG covers goals, shots on goal and misses. Shots are counted from the play-by-play.

Typical game. The middle value across Buffalo games in the 2020–21 regular season, counting both teams (112 team totals), so it stands in for a league-average game. A sentence at the top only appears when a number is among the highest fifth of those, or when a goal went in while a team was pinned.

Shots at an empty net are left out of every row. None of this says why a goal went in: a unit that cannot change is pinned and tiring at the same time, so these rows describe when the danger came, not what caused it.

GP

Games in which this exact line/pair shared the ice together at 5v5.

TOI

Time on ice together at 5v5, meaning the whole line/pair on the ice at once, not any one player's own total. Only the seconds that exact pair or trio was the unit count, which is why a pair's TOI and xG% here differ slightly from the WOWY table, where together counts every 5v5 second the two share, whoever else is on the ice.

xGF / xGA

Expected goals for/against while this combo was on the ice, from this site's own xG model.

xG%

Share of on-ice expected goals this combo earned: xGF / (xGF + xGA). The single best read on who controlled play.

GF / GA

Actual goals for/against while this combo was on the ice together.

CF / CA (Corsi For / Against, Shot Attempts)

"Corsi" is just the hockey-analytics name for total shot attempts: shots on goal, missed shots, and blocked shots combined, a volume proxy for who had the puck more. CF is this combo's own attempts, CA is the opponent's.

CF%

Share of on-ice shot attempts (Corsi) this combo earned: CF / (CF + CA).

CF% Rel

This combo's CF% minus the team's own CF% in the minutes this exact combo was NOT on the ice. Positive means the combo lifted the team's play; negative means it dragged it down.

xGF% Rel

This combo's xG% minus the team's own xG% in the minutes this exact combo was NOT on the ice. Positive means the combo lifted the team's expected-goals share; negative means it dragged it down.

FF / FA

Unblocked shot attempts (also called Fenwick): shots on goal plus misses, excluding blocks. One layer closer to real scoring chances than CF/CA.

SF / SA

Shots on goal for/against while this combo was on the ice together.

Minimum Ice Time

Drag the slider on each table down to see combos with less shared ice time. Their percentages get noisier the lower you go, since a combo that barely played together can swing to 100% or 0% off a single shot.
