I imagine many of you may have already seen this article, but if you are interested in fielding then you need to see it:

This is basically discussing the best fielding analysis that is publicly available.  I guess it's not exactly Angel-centric, as not one of our players is amoung the 3 best or the 3 worst at their position.  But every once in awhile it comes up here as to exactly which defensive stats are good, and this is the best one.  (For day to day numbers you can use unadjusted zone rating, but you need to take that with a grain of salt.)

P.S. I still say the best defensive CF I have ever seen is Gary Pettis.  He even won a gold glove in his 2nd full season, which is basically unheard of.
