Did you notice that a huge number of foreign Olympians live and train in the US and many have duel citizenship?
Its been like that for years. Same with gymnastics. I think there is a major training facility in Hackensack and I think gymnasts train in Denver - not sure with the Karoly coach.
I did, your point
I thought it was interesting that they're US citiens, train here, work here, school here then play for the fatherland. I think most weren't good enough to make the US team.
