|About the stats|
Over the course of his career, Harmon Killebrew made 9,833 plate appearances. Killebrew was worth 60.6 Wins Above Replacement and 28.0 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 60.6 WAR becomes 60.6 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 28.0 WAA becomes 32.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Killebrew 119.8 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).
Harmon Killebrew has a Hall Rating of 112, making him a member of the Hall of Stats.
