|About the stats|
Over the course of his career, King Kelly made 6,457 plate appearances and pitched 45 innings. Kelly was worth 46.0 Wins Above Replacement (47.0 as a hitter and -1.0 as a pitcher) and 24.2 Wins Above Average (25.7 as a hitter and -1.4 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 46.0 WAR becomes 62.7 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 24.2 WAA becomes 30.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Kelly 117.1 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).
King Kelly has a Hall Rating of 110, making him a member of the Hall of Stats.
