All these metrics are incredibly valuable and need to be considered in all discussions. However, I think we lose sight of the fact that when you are watching the players a substantial amount you can interpret stats In a different way. When I watch Miller pitch I am surprised when hr struggles. That to me means more than his FIP. I feel this is sustainable because I don't see him getting squared up and see his nasty stuff that he locates well.
Did you previously feel that way about Teheran?
