Over the course of his career,
Buster Posey
made 5,607 plate appearances.
Posey
was worth
44.9 Wins Above Replacement
and 27.1 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 44.9 WAR becomes
51.9 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 27.1 WAA becomes 32.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Posey 109.9 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).
Buster Posey has a Hall Rating of
103,
meaning he will be in the Hall of Stats when eligible—but very close to the borderline.
