Daft idea maybe - but what's the chances of the NFL actually awarding a franchise outside of the States? I know the interest in Latin America is huge, especially Mexico, but Europe could be the sporting equivalent of a Gold rush to the game if tapped correctly. Both with regards to the whole financial picture (investors/fans buying merchandise etc) and also with regards to actual playing talent.
Maybe that would take us too much towards a proposed world league or something stupid like that, plus it could, only could mind, sound a death knell to the BAFL (or whatever it's called). On the other hand though it could bring even more interest into the game, and garner more interest in the game over here.
