Djokovic's competition was Flo Mayer. Murray gets cult favorites like Fat Dave and The Fog. NID
Mayer got almost the same votes of Djokovic, while here the only possibile player who can get more votes is Nalbandian IMHO.
I already said these are made randomly, otherwise I would have not put my faves in terrible groups (like Troicki, who is 100 % going out).
