|About the stats|
Over the course of his career, Matt Williams made 7,595 plate appearances. Williams was worth 46.8 Wins Above Replacement and 23.0 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 46.8 WAR becomes 48.1 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 23.0 WAA becomes 26.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Williams 95.1 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).
Matt Williams has a Hall Rating of 89, leaving him short of induction to the Hall of Stats.
