Cora played for Francona, and Tito was always known as a players' manager, a guy who took care of his men (even when fullgrown boys like Manny earned whatever static he deserved from the media, opponents, even teammates).
So maybe AC learned a bit about managing just from observing. Scheduled days off aren't a bad thing -- unless you're a fan who saved up and can only afford to attend one game, and your favorites aren't in the line-up.
I know some posters don't like this, but is it really just coincidence that the Red Sox have had losing records every single August of the Bloom Era... after what many fans, media, and especially players felt were insufficient reinforcements at the trade deadline.
