|About the stats|
Over the course of his career, Bill Champion pitched 804 innings and made 109 plate appearances. Champion was worth -1.0 Wins Above Replacement (-0.9 as a pitcher and 0.0 as a hitter) and -8.1 Wins Above Average (-8.2 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -1.0 WAR becomes -1.2 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 -8.1 WAA becomes 0.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Champion -0.3 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).
Bill Champion has a Hall Rating of 0, leaving him nowhere close to induction to the Hall of Stats.
