I was checking out the USOC site, and it looks like before 1995, all of the teams were neighborhood teams, with no sign of NASL or A-League teams. Why didn't they participate? And in modern times (yeah, since 1995), how far has any USL-2 or PDL team ever gone? I saw that the Rhinos have been to the finals twice, winning it once, which answers how far an A-League (USL-1) team has gone. thanks.
