...e rating, throwing errors, as well as catcher and of throwing arms?
I've read the excellent offense vs defense article by Dean Carrano. Are there any similar things about any or all of these other defensive ratings and their impact on the game?
I think far too many people undervalue a catcher's T & PB rating. A catcher with a T20 rating could make 40 throwing errors in a season. And a catcher with a high PB rating can kill you.
