|About the stats|
Over the course of his career, Billy Herman made 8,641 plate appearances. Herman was worth 57.4 Wins Above Replacement and 28.7 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 57.4 WAR becomes 58.7 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 28.7 WAA becomes 29.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Herman 112.0 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).
Billy Herman has a Hall Rating of 105, making him a member of the Hall of Stats—but one who sits very close to the borderline.
