It really shouldn't come as a surprise, but it's nice to be reminded of just how awesome some guys were. Andruw Jones is easily the most valuable defensive player of the UZR era. He's been (to date) 137.9 runs above average. The next closest player in the UZR era (for Fangraphs, that's since 2002) is Carl Crawford at 108.2, and Carl Crawford is a left fielder.
In case you didn't know, UZR is based on average runs per position, so a +15 in LF is not the same as a +15 in CF, because your average CFer is much better than the average LFer. The next closest guy who's been mostly a CFer in the UZR era is Coco Crisp...at 58.7. Meaning, he's been over twice as valuable as any other centerfielder. In fact, he's made it very difficult for other centerfielders to rate as above average because he single-handedly skewed the metric.
Of course, Franklin Gutierrez is up there (60.7), and he had one of the best defensive years ever in CF last season. In his career, only about half of his innings are in CF, but they were pretty much all last year. So, all he has to do to reach Andruw's 137.9 is to replicate that season 3 more times. And it's possible he's better-Andruw only posted higher than +29 one time...in 2005. But of course, Andruw played 4 full seasons in CF before UZR starts counting.
Just something worth remembering about Andruw Jones-how utterly, utterly dominant he was defensively in CF. Just makes me wonder how many years we were a fringe playoff team that was carried in on just the strength of his glove. He certainly was robbed of the MVP in 2005, for one.
