If I was a legislator in a major metropolitan area and a team threatened to leave, I would call bullshit on it. There’s a finite amount of major metro areas in the US (and an even a smaller subset if you remove all the ones that currently have sports teams), so there’s a limit to what’s economically viable if the potential attendance/sales revenue is coming from a dedicated local fanbase. For example, if the NY Jets ever threatened to become the Santa Fe Jets if taxpayers didn’t front a new stadium bill, I would go ahead and let them.
