Interresting question. Defniteily those 2nd tier guys after top 4 currently would play F, SF between them - so Ferrer,Tsonga,Berdych, Delpo as in ranking now 5-8 would be 1-4 seeded. Also this 4 guys are better than rest of top 10, top 20
AO - Berdych or Tsonga depending on form. Ferrer is great but someone from those big hitters would overpower him.
Delpo´s fitness in AO heat probably wouldn´t let him to win
RG-Ferrer or Delpo. Not much to say else
Wimbledon - Tsonga-Berdych F i would favour here Berdych, because Tsonga´s ROS really is horrible
USO - Delpo - Tsonga - probably Delpo - he can deal with Tsonga, great H2H vs him, only serve and explosive game has better Jo, but Delpo is more consistent, stronger BH, ROS, deffense
Than 2 guys who can do something - Monfils if healthy and not clowning all the time can do something at RG and Robin if healthy - who knows if he will be back
