No use to ponder on if... history is not written by "if"s

* It is remarkable for a player to stay healthy. Look at Nadal's knees and Djokovic's back. They are just 20.

* The wind behind Djoko's back: it certainly impacted him. However, players switch sides in tennis. The wind does not pick just one player and forgets the other.

* Considering all the factors that can impact a player's ranking, it is amazing for someone to stay at #1 ranking for 3+ years CONSECUTIVELY. Give talent its credit and enjoy it when you can. No one is eternal - players and viewers alike. Remember what TMG said, "you can never be bigger than the game itself."
