re: How would an NFL team in London even work?

I posted in one of these threads one time that you'd almost need a full division to really make it work logistically although I think that would be pretty stupid. You'd need 3 regional all inclusive training facilities in US and 1 or 2 in Europe for travelling teams.

-3 away games for euro teams would be in Europe, this would then require only 5 more games in America which could be done in two 2 game trips and other trip.
-the cross conference and cross division opponents could play their 2 euro away games back to back and be done.
-the other 2 same placing conference teams would be the other two teams with the potential of travel.

TLDR Basically the European teams would get 11/16 games in Europe between their home and the other 3 European teams and the American teams going there could knock out their 2 away games against the European teams in one stretch.
