If the state (tax payers) do not pay for a new stadium, then the owner threatens to move the team to another city that will pay for a new stadium.
And that is nothing new. Going back to Walter O’Malley in Brooklyn in the 1950s, teams have tried to get stadiums built, and subsidies used to help underwrite it all.
How do you know?
Feel free to name another city that can generate the fan base.
