Graph Of The Day: Range Factor

Yesterday, I posted a graph that showed quite conclusively that Fielding Percentage is a meaningless statistic when talking about defensive impact on runs allowed. As commenter CoachOfEarl brought up in the corresponding thread, a slightly more advanced statistic called Range Factor (RF) also has disagreements with UZR. We see this specifically in the case of Adam Jones, who has the best RF in the majors and yet has a -13.1 RngR (the range component of UZR).
