Over the course of his career,
Jack Chapman
made 510 plate appearances.
Chapman
was worth
0.9 Wins Above Replacement
and -0.8 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 0.9 WAR becomes
1.8 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 -0.8 WAA becomes 0.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Chapman 2.0 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).
Jack Chapman has a Hall Rating of
2,
leaving him nowhere close to induction to the Hall of Stats.
