|About the stats|
Over the course of his career, Bobby Grich made 8,220 plate appearances. Grich was worth 71.4 Wins Above Replacement and 43.6 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 71.4 WAR becomes 72.9 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 43.6 WAA becomes 43.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Grich 150.3 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).
Bobby Grich has a Hall Rating of 141, making him a member of the Hall of Stats.
