|About the stats|
Over the course of his career, Brian Roberts made 6,253 plate appearances. Roberts was worth 29.4 Wins Above Replacement and 8.7 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 29.4 WAR becomes 29.4 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 8.7 WAA becomes 13.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Roberts 53.0 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).
Brian Roberts has a Hall Rating of 50, leaving him nowhere close to induction to the Hall of Stats.
