|About the stats|
Over the course of his career, Johnny Allen pitched 1,950 innings and made 786 plate appearances. Allen was worth 26.4 Wins Above Replacement (27.9 as a pitcher and -1.4 as a hitter) and 8.7 Wins Above Average (10.1 as a pitcher and -1.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 26.4 WAR becomes 27.5 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 8.7 WAA becomes 15.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Allen 55.0 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).
Johnny Allen has a Hall Rating of 52, leaving him nowhere close to induction to the Hall of Stats.
