Man, I guess I either need to have my eyes poked out or I a need a crash course in advanced metrics. My understanding of UZR/150 is that a "normal" center fielder would have a UZR/150 of 0 and all calculations area a deviation from 0. If I read this correctly Bradley Jr. has a UZR/150 of -14.6 and is 20th out of 24 in range factor. Ellsbury, OTOH, is 6th in Range Factor with +13.2. This proves what I've always suspected, that when it comes to statistics, eyes are absolutely useless.
WAR, of course, which uses range factor in its calculations, is the be-all, end-all of statistics. /s/
Could it be that we've become so obsessed with statistics that we can no longer see the forest for the trees?
