|About the stats|
Over the course of his career, George Grantham made 5,900 plate appearances. Grantham was worth 33.6 Wins Above Replacement and 14.3 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 33.6 WAR becomes 34.4 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 14.3 WAA becomes 15.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Grantham 61.8 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).
George Grantham has a Hall Rating of 58, leaving him nowhere close to induction to the Hall of Stats.
