Have no idea which is the favored defensive metric of the moment, but if people are saying Dansby's more "solid" than Gold Glover, that wouldn't exactly put Lewis in Pache territory, would it?
OF defense is much easier to quantify than IF defense since the vast majority of OF defense value is from catching flyballs with known hang times and landing spots. I would put almost zero stock in any IF defense metric with any more accuracy than roughly tiering guys.
