As for the peak defensive thing, it was from a subscriber article on Bill James online, but was referenced by Rob Neyer here
As with most attempts to analyze defense, it is still quite the wax nose scientifically speaking. I wouldn't consider it fair by anyone in a discussion to speak with absolute authority about this theory. Also, it begs the question on "defensive value." The argument seems to be "defensive skills" more than "defensive value," which would be a category error. Of course, all I can read is a Rob Neyer blurb, so whether this research is confusing categories isn't fair for me to say, just raising the question.
