You might have read Tom Tango’s name in my posts or some other dude’s post. If Bill James is considered Godfather of advanced stats, Tango is Godfather Part II. He created wOBA and FIP, two of the most commonly cited “advanced” metrics today.
What you might not know is that Tango was actually hired by Theo Epstein as a consultant for the Cubs. Yes, one of the legends of baseball analysis used to work for the Cubs. Today, he works with MLB Advanced Media to develop new tools based on Statcast technology.
I bring this up because we just talked about the shortcomings of PECOTA projections [I need to insert link once posted] and defensive statistics [ditto on the link].
