He asks the $100,000,000 question "How does one figure out how to measure how well a catcher frames pitches?" then he doesn't answer it.

Maybe MASN wasn't the venue for the technical details.

there are certainly issues with measuring pitch framing and one should see it more as a litmus test. Responsibility is shared by a pitcher and a catcher, and there is a great deal of work trying to sort out exactly who should earn credit.

Right, he says there is work to be done but doesn't explain how they are doing it. I have not seen anyone of the current generation explaining how they come up with their numbers.

Sorry I need the curtain to be pulled back before I buy into a system.

They have a comment section on that article.

Could get pretty "Mathy" Corn. Seriously, I do recall reading something about how they do it somewhere though.

I'm good with theory, it is just the actual higher math that gets me.

I would rather have it out there and have to ask for help in understanding it then for them to be pulling the Wizard of Oz routine.

I imagine you would have difficulty with some of the step by step works because these systems are often proprietary. Raw numbers from pitch f/x are pretty simple and straight forward.

And filled with so much background noise as to be worthless.

I understand why teams' systems should be proprietary, I am less sure why anyone in the broader stat community would want to restrict knowledge in that way.

How does the background noise make them worthless? Similar background noise amongst all catchers and the differences are highly repeatable. That repeatability indicates a skill.

Because they are getting snatched up by the clubs.

Right, being secretive kept Voros McCracken and Mike Fast from getting jobs with clubs..oh wait it didn't.

It did prevent Voros McCracken. He has often mentioned that. Knowledge is their currency.

He got a job with a team, he then lost it.

He sure did. He then said he had trouble getting picked up by anyone else because they wanted him to have another big find.

That guy who came up with pitch framing never released even the nuts and bolts of his college pitch handling system because that is worth a lot to a team.

The guys who do projection models keep it proprietary. These things have value and it makes sense to hold onto that value if you created it.
