Soccer will definitely take off in the US. Too much money behind it. Most popular sport in the world, and the money to be made with US leagues is tremendous. What is truly ironic is that soccer is among the most popular sports for youth in the US who go to summer camp--and grade school. But for whatever reason, it never seemed to go beyond high school interest. No question it will be big. Bringing B to the US was a genius move IMO.
Add to the equation the number of South American immigrants in the US; football is very popular in Mexico & Latin America.
