Good discussion. I'm a 'stats' guy. Love WAR for the weighted system it offers. I'm not quite on board for how the metrics are kept for defense (UZR) just yet.
As many others pointed out, positional weighting can really put a player in a very good light when the position is particular weak for that year. e.g. Donaldson, Gordon.
For those who don't think Gordon is a good defender - the guy impresses the crap out of me. One hop off the fence, no hesitation, on a rope, right on the bag. Time after time. He probably turns 60-70 doubles a year into singles or 7-4 put out. If he was a catcher, his 'pop time' would be under 1.4 secs (for catchers, pop time is pitch from ball received to 2B). Heyward also...a 6'4" galloping ghost. Basically a faster Ken Griffey, JR. (also tall, at 6'3"). Now are their values as high as they should be for WAR? I don't know. I don't think so. But they are elite defenders from the eye test.
SABR doesn't like the SB...but I do. I wish there was a better way to metrically track going 1st to 3rd base on a single to the outfield for a runner. Stuff like that. To be an elite SB player, e.g. 50+ SB talent at 90%+ success rate is going to cause more damage than most metrics will currently track.
I like war, but you have to appreciate linear weights, weighted outcomes, and so forth to get at all excited about WAR. If those don't give you a mental 'up' then WAR won't. I'd then resort, for just being impressed with defense for what it is and then, for hitters, go with OPS+.
