Which was my point that JV doesnt understand the conversation so he should stop posting. I am trying to move this into an analysis of those concepts, but he cant get past step 1.
Yeah, except this isn't an MLB forum. Most people, including big time baseball fans, don't understand and don't want to understand Sabermetrics. On the forums on Fangraphs, that's an appropriate place to lambaste someone for not getting these concepts. This isn't. Most people playing this game don't care about using Sabermetrics to measure real-life baseball, and you and I and Bobzilla are not going to convince them, and in any event, that's not the topic of this thread.
As I've said like 10 times in this thread, every Advanced Metric, including the concept of replacement level, is unmeaningful in HBD.
The idea of FIP, for example, is not a logical fact in real life. It is a hypothesis that might or might not be true, which happens to have been proven to be functionally true by testing it against huge amounts of actual data. In HBD, it is an untested hypothesis, which is another way of saying it is a meaningless theory until it is tested (a test I'm confident it would fail here).
The idea of replacement level would certainly be applicable to HBD, at least in theory. But how to measure that would require a large amount o ftesting that has not been done (and probably never will be), so it is also not meaningful at this point.
