|About the stats|
Over the course of his career, Johnny Mostil made 4,103 plate appearances. Mostil was worth 24.4 Wins Above Replacement and 8.6 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 24.4 WAR becomes 24.7 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 8.6 WAA becomes 10.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mostil 42.9 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).
Johnny Mostil has a Hall Rating of 40, leaving him nowhere close to induction to the Hall of Stats.
