Why Isn't Rugby More Popular in the USA?

I just watched a rugby tournament on one of the NBC network channels. Rugby is not on tv very often, but when it is, I usually watch it. I don't know much about the sport, but it is entertaining. Rugby is basically a combination of American football, soccer, and a little bit of wrestling. These guys are more physical than football players and they don't even wear any pads!

With the Superbowl happening today it got me thinking. The Superbowl is one of the most watched events. When you compare football and rugby, rugby seems to be a lot more entertaining. Comparatively, football is much slower. There is a lot more action in rugby. I think if Americans were more exposed to this sport and they learned the rules, this sport would pick up in popularity.

Update 4-8-15 Rugby still does not get much coverage in the US at least not on the major networks, but a while back, they did have a special with the New Zealand All Blacks coming to the US for an exhibition game against the USA team. 

Of course the All Blacks one by a lot because they are one of the best teams in the world, but it was still fun to watch.  Hopefully this sport gains some more popularity and we get to see more coverage soon!
