Yup. When you become the owner, you get to make the decisions...if you want to.
If you're smart, you learn early that it's helpful to delegate and have football-people make football decisions. Your role evolves to being Chief Arbitor of Internal Disputes, Question-Asker & Chief, Source of Sage Wisdom and Provider of Additional Support When Asked For or Needed.
But all owners aren't smart. Hopefully Michael is. In any case, he owns the store, and he and his family get to spend the money the way they want to. (It's the American Way).
I would say the Rooney family runs an organization like one should be run. They appear to be very good at delegating authority to people who are experts. Same with New England. Jerry Jones has decided he is the HC, GM, and everything else. It is his money and his team so he has said. I really do not know what he Cardinal organization is or is not.
