|About the stats|
Over the course of his career, Ken Johnson pitched 1,737 innings and made 595 plate appearances. Johnson was worth 17.8 Wins Above Replacement (20.2 as a pitcher and -2.4 as a hitter) and 1.8 Wins Above Average (4.1 as a pitcher and -2.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 17.8 WAR becomes 18.2 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 1.8 WAA becomes 7.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Johnson 31.5 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).
Ken Johnson has a Hall Rating of 30, leaving him nowhere close to induction to the Hall of Stats.
