Advanced Metrics Newsbeat

Thursday, May 30, 2019

Not bad for a summer job, but are baseball’s ‘advanced defensive metrics’ accurate?

Slog through the fine print of advanced baseball metrics and you often find a passage that says, Yeah, these numbers might not be accurate, but it’s the best information we’ve got, so let’s go with it.

Which is pretty much the same thought process that led to the belief that the Earth was flat, the sun orbited around it and a good way to identify a witch was to tie her up and throw her in the nearest lake to see if she sank.

“Sure, we might be ‘wrong’ and drown a few people, but it’s the best system we’ve got.”

Here’s the problem with that: When we accept and use these numbers without question we give them validity, and players are now being judged by metrics that even the metrics’ advocates admit may not be accurate.

I’d trust the opinion of a coach or scout who has watched thousands and thousands of baseball games and tens of thousands of players far more than the opinion of a “video scout” watching a game on TV, making $8 an hour, doing a summer job and feeding what may or may not be accurate data into a flawed system.

So why do we continue using these numbers?

Because we want to have opinions without going to the trouble of developing expertise.
