That's nbetter, right? They've changed Minkiewicz for Delgado--that's a downgrade, right? They've changed Diaz for Nady--that's pretty mich a wash. They've changed Piazza for Lo Duca. That's clearly an improvement--except Lo Duca is throwing out runners worse than Piazza did. So where's the improvement coming from defensively? I would argue that Lo Duca's so much better at catching than Piazza that, even though he's throwing worse, he makes up for it with the rest of his game. If you've got a better theory, let's hear it. The obvious answer is, they're giving up less runs because of the pitching. If you think switching Piazza for LoDuca is the reason why they're giving up 3.08 runs per game, you are a silly, strange man. Or someone who hates Piazza with a passion that eliminates all rational thought.
