You just worded my thoughts a lot better than I did. Obviously they have an analytics team and solicit opinions, but overall I've seen no evidence that the Beeston/AA team is pushing any boundaries. It doesn't take a genius to realize that Donaldson, Price, Tulo, Martin, etc.. are good players.
He's probably improved a bit from the dark days of trading Napoli for Francisco, signing Cordero because ERA, and giving everyday starting jobs to JPA, Thames and Sierra, but I'd be comfortable saying a good portion of this forum is more familiar than AA with baseball analytics.
