|About the stats|
Over the course of his career, Johnny Callison made 7,437 plate appearances. Callison was worth 38.5 Wins Above Replacement and 11.2 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 38.5 WAR becomes 38.5 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 11.2 WAA becomes 18.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Callison 71.4 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 Callison has a Hall Rating of 67, leaving him short of induction to the Hall of Stats.
