I don't understand this argument. The back-up catcher plays every 5th game or so and is typically the last option pinch-hit AB off the bench. Even a strong hitting catcher won't be the first or even second pinch-hit option. In other words, the role's value is defined in the games he plays, not in his pinch-hit prospect. Would you really sacrifice 32 games of defensive performance for a few dozen (at most) extra PH opportunities? um yeah, I never said a single word about pinch hitting. i see (kind of) what he's saying, but he's forgetting that the backup C still has to hit in those 30-some odd starts.
