Over the course of his career,
Tom Seaver
pitched 4,783 innings
and made 1,552 plate appearances.
Seaver was worth 105.3 Wins Above Replacement
(101.1 as a pitcher and 4.2 as a hitter)
and 69.6 Wins Above Average
(65.5 as a pitcher and 4.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 105.3 WAR becomes
107.6 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 69.6 WAA becomes 67.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Seaver 221.8 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).
Tom Seaver has a Hall Rating of 219,
making him not only a member of the Hall of Stats—but one of the very best players of all time.
