|About the stats|
So far in his career, Justin Upton has made 7,649 plate appearances. Upton has been worth 32.6 Wins Above Replacement and 7.8 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 32.6 WAR becomes 32.2 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 7.8 WAA becomes 15.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Upton 59.6 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).
Justin Upton has a Hall Rating of 56, meaning he would not be in the Hall of Stats if his career ended today.
