|About the stats|
Over the course of his career, Nels Potter pitched 1,686 innings and made 628 plate appearances. Potter was worth 25.1 Wins Above Replacement (23.1 as a pitcher and 1.9 as a hitter) and 11.9 Wins Above Average (9.7 as a pitcher and 1.9 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 25.1 WAR becomes 26.0 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 11.9 WAA becomes 16.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Potter 55.9 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).
Nels Potter has a Hall Rating of 52, leaving him nowhere close to induction to the Hall of Stats.
