Don't get me wrong, I wasn't putting the US teams down against other continents, just describing a perception.
The only time I have watched a match all the way through was when, as a small child, my uncle was a director of the local 7th-league team. He took me to a match, in a (failed) attempt at bonding, but I really just spent the time standing, shivering, and wondering why these grown men were doing PE, on purpose, in public.
