Join Wayne Winston for an in-depth discussion in this video Examples of good and bad metrics, part of Wayne Winston on Analytics.

But what's the flaw on fielding percentage?…If I never move, I'll have a good fielding percentage.…The balls that go five feet to the left of me and five feet to…the right of me, I'll never get to, and they'll never be called an error.…So Bill James, who you may have heard of, who's sort…of the father of saber metrics, started as a night watchman in…Lawrence, Kansas.…
