What advantage do the Packers have over other franchises because they're publicly owned? ...just curious
I can give you my take on that.
If the "Home Town Team" has a bad owner, the fans are screwed. There is very little that they can do to change the situation. If they support the team in spite of the owner, the owner has little incentive to change. If the fans don't support the team, the owner may move the team.
All the fans can do is wait and hope that the owner will sell the team to someone better. But the next owner may not be better.
The thing about a publicly owned team, as well as a publicly owned company and a democratic government, is that there is the possibility of change when things are not working.
I would be more optimistic about the shareholders of a publicly owned team fixing things than I would be with a publicly owned company. For the most part, if someone does not like the way a publicly owned company is being run, he sells his shares.
Teams are a lot simpler to make work than governments. Basically, you hire a good general manager, establish a long-term philosophy, and let the GM do his job without interference.
Also, I also suspect that, in many cases, community ownership would greatly increase community support for the team.
