|About the stats|
Over the course of his career, Scott Rolen made 8,518 plate appearances. Rolen was worth 70.2 Wins Above Replacement and 44.1 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 70.2 WAR becomes 70.2 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 44.1 WAA becomes 45.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Rolen 151.7 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).
Scott Rolen has a Hall Rating of 142, making him a member of the Hall of Stats.
