|About the stats|
Over the course of his career, Cap Anson made 11,331 plate appearances and pitched 4 innings. Anson was worth 94.5 Wins Above Replacement (94.4 as a hitter and -0.1 as a pitcher) and 55.5 Wins Above Average (55.4 as a hitter and -0.2 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 94.5 WAR becomes 127.9 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 55.5 WAA becomes 56.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Anson 230.0 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).
Cap Anson has a Hall Rating of 216, making him not only a member of the Hall of Stats—but one of the very best players of all time.
