|About the stats|
Over the course of his career, Billy Williams made 10,519 plate appearances. Williams was worth 63.6 Wins Above Replacement and 27.1 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 63.6 WAR becomes 63.7 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 27.1 WAA becomes 30.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Williams 118.4 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 Williams has a Hall Rating of 111, making him a member of the Hall of Stats.
