Nadal is a clear #2 in the current ATP Race with the only part of the season including his worst surface of the 3 major surfaces: hard courts. He has not even set foot on his 2 best surfaces clay and grass, yet is still a clear #2 in the race. Yet he should be in a poll about someone who would finish only #3?
Novak Djokovic is a clear #1 in the current ATP Race, last year performed well on all surfaces, and currently leads the #3 in the ATP Race by a whopping 140 points already. Again so he should he be included in a poll about the year end #3 why exactly??
Since you seem insistent on comparing Federer to two men out of his league these days, rather then comparing him to his peers of tennis like Roddick and Davydenko, I will enlighten you a bit. Federer is almost 100 race points behind Nadal already and the only surface that men have played on up until now is hard courts, Nadal's worst surface and Federer's best. Nadal has not even set foot on grass or clay and is already almost 100 race points ahead of Federer anyway. Federer has been unable to even come close to keeping up with Nadal on Nadal's worst surface. Djokovic is already a whopping 171 race points ahead of Federer after less then 1/3rd of the season, and while hard courts is Djokovic's best surface it is also Federer's. It does not take a brain surgeon to see certain things.
