|About the stats|
Over the course of his career, Bill Terry made 7,109 plate appearances. Terry was worth 55.8 Wins Above Replacement and 33.5 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 55.8 WAR becomes 57.3 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 33.5 WAA becomes 34.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Terry 118.6 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).
Bill Terry has a Hall Rating of 110, making him a member of the Hall of Stats—but one who sits very close to the borderline.
