Hahaha... I so much pity all the American and Canadian guys who have no idea about this sport.
I remember in the first few years when I was here I had many "fights" with friends and co-workers about football (soccer) vs American sports.
One thing almost all those who have no idea about this sport said is that it is not a real contact sport, not masculine enough, and Americans like only those sports. Well, this is the most ridiculous argument ever...
Have you guys ever watched replays from the game? Have you seen the rock hard tackles, falls, head clashes those players are having, everything in full high speed, and all that without almost any protection equipment - unless you consider those small shin pads they have?
Compare this with the "armour" the American football players have on.
