Why do American football players wear tights and so much padding?

Why do the American version of rugby players wear tights and so much padding?

• The normal version of rugby players don't wear such stuff even though it involves more collisions by massive guys and is more dangerous.

• Answer:

  It is more dangerous, because they don't wear padding. Football I would say has a much higher injury rate, as it is much more full speed full contact. They know they can hit harder, because of the padding, and several of them use steroids to try to improve performance. Rugby may have alot of big players, but I doubt they have the resources to try and find the biggest players........that's what football does. Don't get me wrong, I'm not knockin rugby players, it is a rough and brutal sport, a mans sport. I just think that football is more dangerous, because they step everything up.
