|About the stats|
So far in his career, Greg Holland has pitched 459 innings. Holland has been worth 11.5 Wins Above Replacement and 5.2 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 11.5 WAR becomes 13.8 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 5.2 WAA becomes 9.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Holland 30.3 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).
Greg Holland has a Hall Rating of 28, meaning he would not be in the Hall of Stats if his career ended today.
