F/O did a good job of replacing the departing players, either via FA or trade, with cheaper alternatives like Smoak, Estrada, Saunders. Even in terms of depth with guys like Carrera, Barton, Colabello.
And even though we'd all prefer Pillar as a 4th OF, he has outperformed Anthony Gose so far which is pretty big when you traded Gose for Travis.
