just FYI, Duo, no, rugby is not a very popular sport in America. I'd say it's pretty far down there on the list.
bóng bầu dục Mỹ = American football. Apparently Bầu dục = the shape of the ball
Hi Duo staff, are you taking these intelligent suggestions seriously and make changes?
American football is not rugby. it's a very different game. players run holding the ball but the rules are very different
Rugby fastest growing sport in US. US Eagles have competed in most of the world cups. USA Rugby has 125,000 members playing in 2,673 clubs as of 2016. So, yes, it is very popular. In this case, Duolingo creators and contributors know more than most about rugby in US.
American style football is essentially a bunch of big thugs in heavy protective gear, trying to work something out. Rugby and soccer a far superior sport of skill.
