The name football comes from the fact that it was played _on_ foot by the commoners, as opposed to the equestrian sports played by the nobility.

https://en.wikipedia.org/wiki/Football_(word) suggests neither definition has definitive support, giving a counter-example:

> Conversely, in 1363, King Edward III of England issued a proclamation banning "...handball, football, or hockey; coursing and cock-fighting, or other such idle games",[7] suggesting that "football" may have been differentiated from games that involved other parts of the body.

But NFL doesn't have all of the other games. It has the season for the league, and that's it. So there's no need to find your team's games in the international tournaments. Or the various providers for any of the national tourneys either. Also, there's only 16 games in the normal season, plus maybe a couple more for play offs. So you're paying a much higher rate for each individual game when you divide the cost per game for the subscription. The NFL is nothing but $$$ grab

Unrelated to your point, but there are 17 games in a season now (and they are floating the idea of 18 games).
