I would guess whoever is the most trusted. I'm not saying this person is directing baseball decisions but is affecting them in a manner suggesting the baseball plans are developed first then reviewed by the business department. It's the only way that makes sense to me, especially after the Cole-Rendon pivot. Lot's of people blame Arte, but I suspect that the true answer of what happened is more complicated. I just don't believe Arte is involved in the details of the business or baseball departments. He is a CEO of a billion dollar corporation, he hires people to be mired in the minutiae. Lastly, think about the standard position that the budget will be extended for the right player. I suspect the major influencing factor for determining whether the player is the "right player" is the business office and not Arte's impulse. This is my Angel conspiracy theory.
