|About the stats|
Over the course of his career, Gio Gonzalez pitched 1,933 innings and made 475 plate appearances. Gonzalez was worth 28.2 Wins Above Replacement (29.7 as a pitcher and -1.5 as a hitter) and 11.7 Wins Above Average (13.2 as a pitcher and -1.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 28.2 WAR becomes 27.6 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 11.7 WAA becomes 17.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Gonzalez 59.3 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).
Gio Gonzalez has a Hall Rating of 56, leaving him nowhere close to induction to the Hall of Stats.
