/A
Indicates that the statistic is adjusted.
/G
Indicates that the statistic is per game played.
+/-
Plus/minus; calculated by subtracting the total number of goals allowed by a player's team while the player is on the ice (at even strength or on the power play) from the total number of goals scored by the player's team while the player is on the ice (at even strength or short-handed).
123
An underline indicates that a career figure is based on incomplete data. For example, shots on goal were not officially recorded for skaters until the 1967-68 NHL season, so Bobby Hull's career total is incomplete.
A
Assists
ATOI
Average time on ice (in minutes:seconds per game)
Age
Age; player age on February 1 of the given season.
ESG

G

GAA
Goals against average; calculated by dividing goals against by minutes played, then multiplying by 60 (the length of a regulation game).
GC
Goals created; calculated by adding goals scored to 0.5 times assists, then multiplying by team goals divided by team goals plus 0.5 times team assists. For example in 2006-07, Sidney Crosby had 36 goals and 84 assists. The Penguins as a team had 267 goals and 468 assists. Thus Crosby is credited with (36 + 0.5 * 84) * (267 / (267 + 0.5 * 468)) = 41.57 goals created. Note that the sum of player goals created is equal to the sum of player goals scored for all teams.
