that doesn't suggest anything of the sortThe smaller the SD the less distance from the best to worst (i.e., data are bunched up). What I find interesting in those numbers is LF. But really, UZR is about as unreliable as a measurement system can be, so whatever. Yes, but it doesn't suggest what he says it does. What it also could suggest is that teams are more willing to throw out a wider range of defenders in the outfield. Some teams might be willing to punt on defense to get a big bat in LF -- e.g., Schwarber -- whereas they wouldn't be willing to do that at second, with someone like Coghlan. Most second baseman are glove-first, slap hitters. So the standard deviation between them probably isn't going to be much. Though, that also might be [expletive]. In reality those numbers suggest nothing.
