Don't you just love how sport brings out the best [aggressiveness] in people!!
As an Englishman who spent some time in Austin, Texas as a youth in the mid-nineties, I must admit to affiliating somewhat with the Cowboys, although I become an avid Packers supporter whilst out there.
But, having said that, it is a silly sport and i concur with xld, there is no justification for calling it "football". It shares more with rugby, but there seems to be an inherant fear with American sportsmen/women of getting hurt, hence the padding!
On a seperate note, I'm considering starting up a new sport in the UK which involves a man throwing a small ball as far as he can whilst 10 opponents try to either catch the ball before it lands, or cause serious injury to the thrower........I shall call it "baseball". There will be a national cup in which English teams (and perhaps some Welsh) will compete. This will be called the "World Series"...........
