|About the stats|
Over the course of his career, Joe Kennedy pitched 908 innings and made 103 plate appearances. Kennedy was worth 7.5 Wins Above Replacement (7.4 as a pitcher and 0.1 as a hitter) and -0.8 Wins Above Average (-0.9 as a pitcher and 0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 7.5 WAR becomes 7.5 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 5.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Kennedy 17.9 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).
Joe Kennedy has a Hall Rating of 17, leaving him nowhere close to induction to the Hall of Stats.
