Americans claim that UK sport ("soccer", aka real football) is too low scoring.
Ehh, those noises are dissipating fast. Soccer has been a fast growing sport and continues to be in the US. I remember in the 90's, if you wanted to watch World Cup games or Euros, or even European leagues, you had to go to a bar with satellite TV, or pay per view in some cases.
There were no soccer fields around to play, no premier league on TV, only one Italian league game on Sundays on the Italian channel.
Now there is an avalanche of soccer and interest in it. Major networks show it, all competitions, all the major leagues. There is growing domestic leagues. Tons of soccer fields everywhere, and lots of interest from youngsters. Also tons of social leagues, where you can compete for fun. I play in one myself.
US is large enough where you can have multiple major sports. American FB will continue to be number one for years to come, but I would not be surprised if soccer becomes top 3 soon.
