The discussion on pitch framing really confuses me. I mean I realize that the skill has been somewhat quantified, at least to the point that there appears to be evidence of both good and bad framers but how do you put a value on a skill that theoretically shouldn't exist at all? Either a thrown ball crosses the strike zone or it doesn't. Shouldn't any good umpire negate any potential WARish gains from a catcher who essentially is good at trickery?
