Sunday is when the Giants and the Miami Dolphins play the National Football League’s first regular-season game held overseas, at sold-out Wembley Stadium in London. For the most American of sports leagues, it is a trial balloon to uncharted territory.

If the game goes well — meaning, mostly, that owners of the league’s 32 teams see that it can cause a happy ruckus in London without the trip feeling foreign to the teams involved — the N.F.L. will likely play two overseas games each of the next four seasons, as part of a resolution already approved by owners.
