Americans love an underdog. The most delicious of the kind is a formally great champion trying to reclaim past glory after it seems far past possible; this well-worn but irresistible anecdote has been replayed over and over in film and sports media and when you couple that with an all time great champion at the tail end of his prime, trying stave off inevitable decline, the story becomes a bit more compelling; add the inherent likability of the individual and the strong belief that the run is nearing its end and you have the most fascinating story-line of this years French Open.
