I think it would be cool.
Yes it would suck to give up a home game although I'm sure JR wouldn't do it if it interrupted his profit stream too much. He's big in the owners group so they probably worked it out so it doesn't hurt the owner, but the fans still have to pay full price for the PSL and home game tickets. THe owner probably gets a big chunk of the international broadcast.
If traveling across great distances wasn't so taxing on the body, there would be a World Football League. Could you imagine an NFL caliber team in the world's greatest cities? How amazing would it be for there to be teams in London, Mexico City, Tokyo, Shanghai, Paris, Berlin...etc.
I imagine it would look somewhat like the international soccer scene. That is still mostly regional, but there are a number of international events such as the World Cup that really are global cultural events.
Goodell must...MUST...be thinking along these lines. How much sense does it make to just keep forcing teams to travel to international cities, disrupt their internal clocks and conditioning, take away a home game, etc...indefinitely? There has to be a bigger picture and it has to be the WFL.
High speed rail could get a team from Toronto to Buenos Aires in like 6 hours. LA to NY in 1 hour. Maybe within the next 30 years this could become a reality.
Hell...they're holding the World Cup in Qatar in 2022...in the fugging desert, in the fugging summer. THe stadiums will be open air and they say they have the technology to cool the inside of the stadium in 110 degree weather. If they can do that...they can put a team in London and Mexico City.
