as far as diving goes, i have seen every team do it, including England, and the USA. But england and the USA dont do it very often deff the least amount of divers in the world cup.
But I do see why they do it, and the simple reason is because its so easy to exploit. Now I understand that its considered low down and cheating, but if some of the players didnt roll around on the ground screaming as if they had just been nutered with out antesia, then the reff might not call a foul. Now like I said I agree that diving and acting do tend to ruin the spot and would love to see it gone but like I said I do see a point to it.
