On the train leaving the ground, one British fan remarks to an American tourist that these games no longer feel significant. He is part of a trio, all wearing different NFL jersey’s, none of which belong to the two teams who played on Sunday. Clearly for lots of British NFL fans going is an annual rite of passage - after all there were 61,000 people watching. But it is no longer the event that immediately sells out, even during an international break from men’s football.
