It seems to me there's an argument to be made that in head to head competition sports (as opposed to "race" or "field" sports), athletes have a much better time accepting the bronze as opposed to the silver medal. Why? Because you actually have to WIN a match to earn a bronze medal, as opposed to losing and being relegated the silver. Case in point? Check out these pics:
Perhaps the silver celebration occurs when you win your semifinal match. But it still must leave a bitter taste in your mouth because you lost (think about Mardy Fish). Both Nole and Bepa seem so happy!
