|About the stats|
Over the course of his career, Bill James pitched 1,178 innings and made 413 plate appearances. James was worth 4.7 Wins Above Replacement (6.0 as a pitcher and -1.2 as a hitter) and -6.1 Wins Above Average (-4.9 as a pitcher and -1.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.7 WAR becomes 4.8 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 -6.1 WAA becomes 2.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives James 9.5 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 James has a Hall Rating of 9, leaving him nowhere close to induction to the Hall of Stats.
