The Packers have shown that public ownership works quite well, thank you. Which is why the owners have colluded to prevent that structure from being replicated.
I am unimpressed with the ability of Jerry Jones to make billions. He may be a good marksman, but he is still shooting fish in a barrel.
Fans should own their teams, it's a better structure. The NFL is out of control, they are a "regulated" monopoly only in theory. That said, I don't give too big of a fuck.
