I think when historians will look back at 2005-2007, they will realize how great Nadal was and not hold it against Fed for failing to win those 3 matches. I definitely don't. Nadal is such a monster on clay that it will take a truly all-time special performance for Fed to break Nadal's career undefeated streak in best-of-5 clay matches. But if ANYONE can pull it off, it's Fed. After all, who could've believed anyone could possibly win 3 slams 3 times? Fed is used to breaking records and pulling off the unthinkable. Will it finally happen this June? We'll see.
