Breslow is the one who hired Bailey, but I think all three guys, Breslow, Bailey, and Cora were/are on the same page. They are all analytics guys, so I would think they have similar philosophies.
At any rate, I just don't share the critical opinions that you have about Cora. I do think there is something amiss with the communication going on in the clubhouse this year, but as far as pitching changes and line ups are concerned, I'm fine with Cora's decisions, for the most part.
