1) They call it Natinal yet the only nation invlved is the USA. S it's kinda like copeting agans yourself.
-It's National BECAUSE the NFL comprises teams from one country. Otherwise it would be international. By the way, on that note, if we took our most well rounded NFL players, the wide receivers, safeties, cornerbacks, etc, we would crush the world in rugby. Rugby is not even played in most high schools here, let alone most colleges at a varsity level, yet we still are ranked 15th in the world.
2) Skill level required is quesionable. I do see how a gywho weighs 300+ lbs who's diet consists of cheeseburgers and fries can be considered an athlete.
-Here's a highlight film of Barry Sanders. http://www.youtube.com/watch?v=0TflnHlQMt8
3) They run fr 10 seconds then stop for 2 mnutes to dece what to do next.
-This is actually similar to soccer. The time spent planning in American football is about equal to the time spent passing around the ball semi aimlessly in soccer. The 11 minutes of actual play in football roughly corresponds to the amount of serious goal scoring effort in soccer.
4) 4 breaks at 15 minute intervals….are you kidding me.
-Football is a much more brutal and demanding sport. I'd wager that soccer players could last at most, a set of downs before their bodies gave out. And to preempt your response, yes, most NFL players CAN run 6 miles. You realize that the 6 miles in a soccer game means that the players are doing about a 15 minute mile? I can walk that. Devin Hester runs five mile hill workouts nearly full speed. A full game of soccer would be nothing to him.
5) They get 4 attempts to move a ball 10 yards. So much for tree strikes and you're out you're so special we'll give yo one more.
-This just shows how ignorant you are-three strikes-you're out is baseball.
6) If you haven't seen your own toes in 5 years chances are you are the best paid player on the team.
-Usually, the highest played player on team is the quarterback. Fat quarterbacks do not exist.
Summary:

Americans are what they are. Loud, Obnoxious know-it-alls who always believe what they have is better then what anyone else has. So I say give it to them. Let them believe whatever they like, let them bask in their own ignorance, why do you think the NFL is so popular? It's all american, then can argue amoungst themselves. The NFL is all they have, even Baseball was tainted when the Canadians won it 2 years in a row. That shut up the americans didn't it.

Changing an american into worldly human being who can appreciate things for what they are is more difficult then understanding what President Bush says half the time. So let them be, let them enjoy their football, and do't mention the fact that the bll they play with looks like a supository.
