Draped was not accurate, he held a large Mexican flag up as he also draped the American flag. There was no place for the Mexican flag in the picture since I assume that Mexico did not give him the opportunity to train, run and compete for the USA.
I'm looking forward to when Mexico gives a gesture of international good will for all that the USA has done for all of the people that have left Mexico for the benefits of the USA, such as Manzano.
I'm also looking forward to big things from Manzano, but I think he learned that he shouldn't pull out one country's flag when he is competing for another. He would never make that mistake again.
