|About the stats|
Over the course of his career, Johnny Bench made 8,674 plate appearances. Bench was worth 75.3 Wins Above Replacement and 46.6 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 75.3 WAR becomes 88.9 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 46.6 WAA becomes 57.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Bench 193.1 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).
Johnny Bench has a Hall Rating of 182, making him not only a member of the Hall of Stats—but one of the very best players of all time.
