Great draw for Murray and Federer: Murray should be comfortable through to the quarters, Federer to the semis. Of the big-4, Djokovic has it toughest but none of them have it too bad.
Mate, I will say that Rafa part is even better than FED and the Andy's one..I really do not see anyone there who can generate some sort of problems to him: Rafa till the quarter he will just walk IMO. And even there, there could be something only if the right Denko is showing up IMO..
On the FED side at the contrary there are a couple of floters who can be difficult to pass: IMO, PHM and Berdy...
So on in all: Rafa should move on without problems till the quarter, FED might be tested before that..But then from the quarter to the semi should be easy..
Djoko is in part of the draw with more floters: If he pass then it will be a great semi hopefully..
Rafa might find someone in the Quarter but no one before and after:
All in all a walk in the park for Rafa IMO
