There are 6 qualifiers in Nadal's section - althought some of them have to play each other. But this should be a benefit for Nadal's shoulder.
I think the top half (with Djokovic) is the stronger half. You have the 'in-form' players on that half (Tsonga, Monfils, Ferrer, Roanic, Ferrer, etc.)
It should be interesting.
I just need to concentrate on Roger's draw.
