|About the stats|
Over the course of his career, John Olerud made 9,063 plate appearances. Olerud was worth 58.4 Wins Above Replacement and 27.5 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 58.4 WAR becomes 59.1 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 27.5 WAA becomes 28.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Olerud 110.0 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).
John Olerud has a Hall Rating of 103, making him a member of the Hall of Stats—but one who sits very close to the borderline.
