No, the analogy works just fine. If it is ‘unfair to the pitcher’ to deal with a variable height strike zone, it is even more unfair to the cobbler to have to make variable size shoes. Were there only one shoe size, manufacturing could be even more efficiently automated; leading to both higher profits for the cobbler, and possibly lower shoe prices for everyone. Unfortunately, in most cases one size doesn’t actually fit all. Having spent as much thought on that as I care to, I have a different question for all: Has anyone asked the pitchers and catchers their preference? If a statistically significant majority of those folks wanted an automated zone, I would reconsider my objections. Is there anything published on this?
