About Player Cards

Player cards present an infographic of a players performance. In this case it shows the player performance over a 3 season span. Each square is separated into three separate sub-boxes with the two smaller boxes on top representing the past two seasons and the larger box on the bottom representing the current or most recent season. This allows the reader to guage how consistent a player has been, and if early in the season it can help identify whether a players performance may be impacted by small sample size and subject to regression or is consistent with recent past performance.

Notes and Definitions
  • The numbers represent percentiles so the higher the better.
  • Percentiles are determined by comparing Forwards to Forwards and Defensemen to Defensemen.
  • Bursts/mi are calculated from NHL Edge Data are are speed bursts above 20mpg per mile skated. The NHL doesn't adjust for ice time so the players that skate more will naturally have more bursts over 20, or at least more opportunity to have more. The NHL also does not provide ice time in the context of NHL Edge Statistics, however, it does provide distance skated. By adjusting for distance skated it will have a similar effect to adjusting for ice time but also adjust for situationional effect. For example, Players don't typically skate as much on the PK, mostly within the defensive zone, so don't get significant opportunity in that ice time to get speed bursts above 20mph. Adjusting with miles skates would account for this better than adjusting with ice time.
  • Sh%AE is Shooting Percentage above Expected (Sh% - xSh%) and is an indicator of how good a shooter is at converting chances into goals.
  • Relative statistics are On Ice - Off Ice statistics and can be an indicator of whether the player makes his teammates better or worse.
  • All data is 5v5 except Shooting Hardest and Average, Skating Top Speed and Bursts/mi which are all situations, ES Average which is even strength (NHL doesn't give a specific definition).
