About Player Cards

Player cards present an infographic of a players performance using a series of Player Archetypes developed for Puckalytics.com and TheStanleyCap.com. The boxes in the rink image show the archetype ratings for the season specified in the card while the graphs to the right show the five-year trends for those archetypes.

Except for Faceoffs, the values shown are the players z-score (standard deviation from the mean) for the specific metric used to calculate the archetype values. When calculating z-scores forwards were compared to forwards and defensemen were compared to defensemen. Positive values indicate the player is above average and shaded in blue, while negative values indicate the player is below average and shaded in punk. The five year trend charts show a range of -4.0 to 4.0.

The value shown for Faceoffs is the faceoff winning percentage rather than their z-score with winning percentages below 50 in pink shades and above 50 in blue shades.

All archetypes are 5v5 except 5v4 TOI, 4v5 TOI, Skating (even strength) and Faceoffs (all situations). Archetypes use regular season data only.
