There was NFL Europa and it was a failure.
If the NFL wants to play a preseason game or exhibition game, or hell even the Pro Bowl in another country fine, but there is no way any regular season game should be played on anything but American soil. It was a huge victory for us Bills fans last year when the team broke their agreement with Rogers and ended our yearly game in Toronto. There have been rumors of having a team in London. It would be a travesty to have a team in London, but yet have San Diego, Oakland or St. Lois lose their team to LA. I wonder if Goodell even considers the local businesses in the markets that a home game is being stolen from when the game is moved to another country. Probably not.
It also helped that the Blue Jays are upgrading Rogers Centre so that it can only permanently host baseball(baseball only stadium),& the only alternative for playing football is BMO Field,which is being refurbished for the Argonauts to be able to play there & with temporary seating,can seat 40,000 fans,10,000 below the minimum that the NFL allows NFL teams to play in. Also,Goodell has been weakened so badly by deflategate,he couldn't stop all three teams,the Chargers,Raiders,AND the Rams,from moving to Los Angeles(the Chargers & the Raiders will share a stadium in Carson,& the Rams' owner will build a stadium out of his own pocket for the Rams in Inglewood). Meanwhile,the Jaguars will move to St. Louis from Jacksonville. So,thanks to Goodell's blundering,Oakland(which really is no loss),Jacksonville,& San Diego will lose football teams.
