I don't know that I agree with this. Nutting's situation with the Pirates is unique because the Pirates are his cash cow, his newspaper company hasn't done well and he ha sold off most of his ownings with Seven Springs I believe.
If you had a rich owner who wasn't relying on the Pirates to make money, I think they would be operated way differently than how Nutting operates them. The issue with Nutting owning the Pirates is that is his main revenue stream, while a ton of other owners wouldn't need to rely on the Pirates for that.
