I'm tired of posting about the reasons why Raiders and Rams left, but it had alot to do with their respective owners and not because LA drove them out. Al Davis left because he wanted another stadium that isn't the LA Coliseum, and even after Irwindale offered him millions for a proposed new stadium, he took the money and ran anyway. And Georgia Frontiere pretty much sabotaged her team and even threatened to sue the league unless they let her move her team, which was back to her own hometown in St. Louis.
And what's ironic about all these is that neither Raiders nor Rams got a new stadium after their relocation, with Raiders rumored to move in with the Niners in a stadium in Santa Clarita, and Rams were promised to get a new public-financed stadium but that promise never materialized. Los Angeles had supported Rams for 49 years so I don't understand what is all these talks about the city not willing to support a football team.
But anyway, if NFL wants to make money, they will go to Los Angeles instead of staying at Jacksonville, which for all their supposed support for the Jaguars, still have games that were blackouted by the league.
