|About the stats|
Over the course of his career, Bob Feller pitched 3,827 innings and made 1,486 plate appearances. Feller was worth 63.5 Wins Above Replacement (65.2 as a pitcher and -1.7 as a hitter) and 31.8 Wins Above Average (33.6 as a pitcher and -1.7 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 63.5 WAR becomes 65.1 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 31.8 WAA becomes 40.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Feller 137.6 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).
Bob Feller has a Hall Rating of 129, making him a member of the Hall of Stats.
