Nadal's level on clay in 12 >>>>>>>>>>> in 11.
2011 was arguably his worst in years, look at Isner taking him to 5. Roger keeping it very, very close
Even having trouble against guys like Andujar. Only the Soderling match was really great.
And then look at RG 2012, guys were happy to win more than 5 games! Monaco grabbing 2. Ferrer, great clay player, sent packing with 5.
