NFL Continues to Blackmail American Cities

In what looks like the latest attempt by the NFL to blackmail US cities into paying them more money, the San Diego Chargers and Oakland Raiders have decided to jointly develop a new stadium just outside Los Angeles. I think that means that at least 3 teams have threatened to move to LA in the past year. One has to wonder if the only reason why there is no team in LA is to make this kind of blackmail possible. If every large city had a team, then cities would know that their franchises would have a difficult time leaving.
