Ok so what I get from rugby is that when they are about to make the hits they always slow down and the follow through is nothing. Now when you have pads on people run at full bore and there is no slowing down and there is tackles being FINSHED.
Anyways it’s proven that American football you get hit a lot harder. So ya
American football > ALL
