|About the stats|
Over the course of his career, Joe Niekro pitched 3,584 innings and made 1,165 plate appearances. Niekro was worth 29.7 Wins Above Replacement (28.7 as a pitcher and 1.0 as a hitter) and -1.6 Wins Above Average (-2.5 as a pitcher and 1.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 29.7 WAR becomes 31.7 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 -1.6 WAA becomes 9.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Niekro 49.5 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).
Joe Niekro has a Hall Rating of 46, leaving him nowhere close to induction to the Hall of Stats.
