lol, Djokovic dominated Nadal, was dominating Murray until he relaxed a bit (maybe he wanted to practice a bit more before the final
), and simply got outplayed in the final by an on-fire Stanimal. It still could/should have gone to 5 sets and who knows what would have happened there, but Djokovic obviously has issues with 4th sets of RG finals, can't seem to get over the hump.
Give Wawrinka some credit, Djokovic was fine.
EDIT: as for the original question....I don't think Nadal will drop too much in the rankings before RG, but even if he does, his aura of invincibility at RG is long gone, and he's not really outlasting people in 5th sets anymore either
