|About the stats|
Over the course of his career, Bill Hutchison pitched 3,079 innings and made 1,425 plate appearances. Hutchison was worth 39.0 Wins Above Replacement (41.2 as a pitcher and -2.2 as a hitter) and 13.1 Wins Above Average (15.5 as a pitcher and -2.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 39.0 WAR becomes 33.1 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 13.1 WAA becomes 13.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hutchison 58.1 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).
Bill Hutchison has a Hall Rating of 55, leaving him nowhere close to induction to the Hall of Stats.
