I don't understand - if he can have an easy year over two year rankings, then he can have an easy half a year over one year rankings. What's the difference.
With Djokovic, I'm sure he was asked if he's upset about losing the number 3 spot, so he probably replied, quite sensibly, that although he's upset it wasn't so bad since in this period he's been playing very well, and has won a tourney, and reached three masters semis.
Djokovic said something about the rankings being 'cruel'.
I'm not totally sure what Nadal's on about, not sure anyone is really.
