FYI, you'll also see a link to catcher "framing".  This year catchers are  
going to receive an additional defensive rating.  It will be listed on the  
card as if it were the catcher's "range" (A thru K).  I'm still working on  
minor details, but basically a subset of range plays will be modified by  
this rating and the overall impact will be roughly the same as 3B/2B  
defense (~40-45 runs/season differential between A and K).

I hope to have another batch of ratings posted next weekend (most likely  
baserunning, OF arms, rest/fatigue).
