Actually, Eraser, it's more than some.
I think it's a lot!

but I think that the helmet and pad thing is a circle.
cause of the way the players hit
if they didn't have the protection, they would get hurt every time.
Rugby is more skilled...sure there are injuries
but I think they teach them how to hit without really injuring players
now gridiron football
the players just hit with abandon.
I used to play full contact gridiron football
when I was young...this was stupid
I remember one guy actually having his collarbone broken on a hit when he ran up through the middle.
