|About the stats|
Over the course of his career, Grady Sizemore made 4,724 plate appearances. Sizemore was worth 27.8 Wins Above Replacement and 12.0 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 27.8 WAR becomes 27.8 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 12.0 WAA becomes 16.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Sizemore 56.8 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).
Grady Sizemore has a Hall Rating of 53, leaving him nowhere close to induction to the Hall of Stats.
