|About the stats|
Over the course of his career, Dave Koslo pitched 1,591 innings and made 571 plate appearances. Koslo was worth 15.3 Wins Above Replacement (17.8 as a pitcher and -2.6 as a hitter) and -0.4 Wins Above Average (2.1 as a pitcher and -2.6 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 15.3 WAR becomes 16.6 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 -0.4 WAA becomes 6.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Koslo 28.3 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).
Dave Koslo has a Hall Rating of 27, leaving him nowhere close to induction to the Hall of Stats.
