Ryan also said that his scouts know statistics.
There is no evidence that his scouts understand statistics beyond the old-time basics. Over and over again reflexive Twins/TR defenders demand 'proof' of this or that observation regarding how old school the Twins are (even though this is readily apparent and openly acknowledged by the organization).
But when TR says "my scouts know stats" or that there are these various unnamed front office people (in addition to Goin), the requirement for evidence goes out the window. We are supposed to take the Twins' word that, along the path to 'getting back to how [they] used to do it', they've also kept up with developments in the game.
To expand on 'mike wants wins' great post: even focusing on particular stats like FIP is a straw man. The forward-thinking organizations develop their own tools and processes. The issue isn't numbers at all, but rather the fundamental approach to management. Teams like Boston, St. Louis, etc., are run like a business - always looking for an edge, incorporating data into their decision making, and so forth.
The Twins approach is obviously very different - something that is rationally undeniable as a result of Ryan's own comments (and others with the organization). They stick to set 'philosophies' and say so proudly. These philosophies are meaningless platitudes about 'playing the right way' and having starters that 'pitch deep into games' (as if anyone would want otherwise), among the slew that are regularly thrown out by the org.
The Twins are a 20th century entity competing in the 21st century. It's a losing proposition.
