To my mind, it's pretty easy to defend. Football is so much simpler to play, you don't need multiple layers of armour, or a "gridiron" (which I understand is actually two words, but for some reason the Americans have missed the space in the middle), and you don't even need an egg-shaped ball, the typical round sort (or a soda can at a pinch) will do fine.
And football can be tough, too. This photo was taken after I took a knee to the face after one enthusiastic game.
Although I tell people that actually I got it by stopping a bus from rolling over a cliff by interjecting my face in the way.
And I think to be honest even the Americans secretly agree, if they don't then why did they manage to do better in World Cup 2014 than England? Obviously it's because they have significantly increased the level of resources invested in the game, there can't be any other possible reason.
Honest.
I'd like to also signpost you towards my new video supporting football, which includes a number of example football plays, and I think clearly shows why football is the greatest game in the world.
Do leave a comment to say if you agree or not (and why), and do check out Tim's blog on the subject to see which of us makes the better argument.
On me 'ed, son!
