Correct. I believe the dangers with American football is the use of the helmets in particular. It allows for tackles that normally would not be possible without the attackee injuring themselves. Refer to Rugby or Australian Football for comparisons.
Hmm yes American football is worse than the others but this overall problem makes me really concerned for rugby. Head injury issues and the subsequent legal exposure is only starting to become an issue taken seriously in the sport. Frankly, the sport doesn't have the money that the American football system has to be able to survive an onslaught of legal cases.
