Season by season
Every season is drawn on the same scale, so bar length is comparable top to bottom. Bars left of the center line cost the team goals; bars right of it earned them.
A player's rating is his percentile among NHL forwards — a 70 means he is better than 70% of them. It is measured from wins above replacement, the number of wins he adds compared with a player freely available to any team. See the full roster table or read how this is calculated.
