|About the stats|
Over the course of his career, J.P. Howell pitched 619 innings and made 13 plate appearances. Howell was worth 7.9 Wins Above Replacement (7.9 as a pitcher and 0.0 as a hitter) and 2.1 Wins Above Average (2.1 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 7.9 WAR becomes 9.5 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 2.1 WAA becomes 6.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Howell 21.9 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).
J.P. Howell has a Hall Rating of 21, leaving him nowhere close to induction to the Hall of Stats when eligible.
