|About the stats|
So far in his career, Greg Holland has pitched 547 innings. Holland has been worth 12.5 Wins Above Replacement and 5.4 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 12.5 WAR becomes 17.0 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 5.4 WAA becomes 10.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Holland 35.2 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 33, meaning he would not be in the Hall of Stats if his career ended today.
