The flack I heard about the Ralph Lauren outfits was that while Ralph Lauren is an American designer, the uniforms were made in China instead of in America, thus costing American textile workers work. If that was the big problem, I don't think they'd care if Roots was founded by an American if the outfits weren't made in America (though for all I know, they were--does Roots have American factories?).
The unaffiliated athletes were great. They had obviously choreographed their entrance with a lot of group dance moves. Not that they were great dancers or that the moves were anything that you couldn't see elsewhere, but they were just so enthusiastic about it and having such a good time. It kind of reminded me of closing ceremonies, when the athletes all just enter in a bunch and they're generally looser and more casual about it. In Albertville in 1992, I remember the male American figure skaters carrying the female skaters in on their shoulders.
