|About the stats|
So far in his career, Jason Heyward has made 6,265 plate appearances. Heyward has been worth 38.7 Wins Above Replacement and 19.1 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 38.7 WAR becomes 40.0 adjWAR. Then, WAA is adjusted by ignoring negative seasons (thus, truly capturing a player’s peak seasons) and making similar adjustments for catchers and relief pitchers. After these adjustments, the 19.1 WAA becomes 21.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Heyward 79.4 wWAR. wWAR is then converted to Hall Rating. A Hall Rating of 100 represents the Hall of Stats borderline (similar to OPS+ or wRC+, where 100 represents league average).
Jason Heyward has a Hall Rating of 75, meaning he would not be in the Hall of Stats if his career ended today.
