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.
You are free to use include player cards in written articles, share on social media, or on other public websites under the following conditions:
Note: The image will update daily throughout the season so if you want to include snapshot then you must download the image.
