Cmath, I highly doubt you watch all of the Phillies games either, so I'm not sure how this makes you more qualified than RiverBrian to talk about the pro/con of UZR. I don't think that watching every game is a prequisite to being able to distrust or trust UZR and other defensive metrics, especially given the fact that there's quite a bit of disagreement in the SABER world on the value of these stats as well. It's not a whole lot different than you and I saying we should not place value on stats like Wins, Losses, and RBIs. I'd caution you a bit here. RB is using the eye-test from his own observations, and you are not. Baseball uses both approaches, and the general consensus of Twins fans watching Revere during his time here was that he was a pretty good defender. I have no problem with you choosing to disagree, but there's no reason to be condescending about it. Thanks,
