Rather than modding you Troll for calling American football a pussy sport I am going to try to defend American Football. (I will be using the term Football to refer to American Football for the rest of this post)
First of all I have to say that in my humble opinion Football is the most exciting/interesting sport to watch as a spectator. The goal off football, unlike soccer, and rugby isn't only about endorse and brute strength, but also relies heavily on strategy and skill. The stoppages between plays is not because the players are wimpy and require a break, they are there so that each side can play their strategy for the next play based upon the current situation.
Yes they wear pads and rugby don't. They ware pads is because when a 350lb linemen hits you it hurts. In football different players are different shapes and sizes, and have different abilities depending on their potion. If they all had the same abilities, it would be boring, and less strategy. Pads allow the 145lb running back to go up against a 350lb linebacker with out being killed.
As far as game play goes. I think what makes football so great is the first down. You have an ultimate goal of scoring a touch down, but you also have intermediate goals, You need to advance the ball 10 yards in 4 plays or you lose possession. Soccer and rugby lacks this intermediate objective, and makes it more boring to watch.
Calling American football a wussy sport is a bit of a disservice. Yes, I am sure American football players would not be very good at rugby. But I also would bet rugby players wouldn't be equally as bad at American football, because, they are different sports, with different objectives and focuses with different rules.
