I had that thought, but it's not like they're cratering his value with bizarre outliers. BIS, Total Zone, UZR, DRS, the Fan's scouting report, and everything I've ever heard about Prince as a defender all agree, he's a poor defender in the neighborhood of -7 runs. Nobody's disagreeing that Fielder is a below average defender, it's the matter of quantifying that I still consider suspect. And what I'm saying is that not only do all the quantitative measures agree to an almost uncanny degree, but even without their presence our best estimate of his defensive value doesn't really move the needle on his value at all. The Fan's Scouting report rated him a 19 out of 100, when the vast majority of 1B rate between 30 and 60. I have a hard time believing he's any better than a -5 defender; there's just no evidence, objective or subjective, to suggest that WAR is overstating his defensive shortcomings. I'm saying I have a hard time quantifying any 1B on a runs or wins level when it comes to defense. It's such an unimportant defensive position, that I really have a hard time caring.
