|About the stats|
Over the course of his career, Ray Chapman made 4,608 plate appearances. Chapman was worth 29.2 Wins Above Replacement and 11.9 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 29.2 WAR becomes 30.5 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 11.9 WAA becomes 12.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Chapman 53.2 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).
Ray Chapman has a Hall Rating of 50, leaving him nowhere close to induction to the Hall of Stats.
