Nadal's going to have to EARN anything he gets with these guys around who are improving and getting stronger mentally. These are his main foes and Nadal hasn't had much success trying to beat Murray and Djokovic back to back. Just to beat 1 of them takes a formidable effort...try beating the both of them. Even Federer struggles to beat them back to back.
Delpo won't be able to hit Ralph off the court ala USO 09,Berdych is mentally not quite there against Ralph either. Murray's mental level is always a question mark so its down to Djokovic to stop him.
