Over the course of his career,
Sam Chapman
made 5,600 plate appearances.
Chapman
was worth
17.3 Wins Above Replacement
and -0.4 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 17.3 WAR becomes
17.6 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 -0.4 WAA becomes 5.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Chapman 26.8 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).
Sam Chapman has a Hall Rating of
25,
leaving him nowhere close to induction to the Hall of Stats.
