|About the stats|
Over the course of his career, Duff Cooley made 5,860 plate appearances. Cooley was worth 15.0 Wins Above Replacement and -4.9 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 15.0 WAR becomes 16.0 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 -4.9 WAA becomes 3.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Cooley 21.6 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).
Duff Cooley has a Hall Rating of 20, leaving him nowhere close to induction to the Hall of Stats.
