you are significantly more likely to be badly injured playing american football than rugby. The only advantage of the american football game is that it lacks the homoerotic rapey nature of British rugby culture (to be clear the issue isn't that the culture is gay it's that it's very weird and bad about consent)
I reckon we could probably collapse the US simply by forcing US football teams to play against international rugby teams in half/half games.
