Back in the 90's , you had the famous Clay court specialist Spaniards who would win French or go deep in the tournament. Then they will not even play at Wimbledon , since they will not be ranked higher there. They will skip or if the play lose in the first or second round. Infact you will not hear about them till the next French open. Will Nadal operate on the same mode, playing only on clay and skip all hard courts to take care of his knee and prolong his career , not really caring about the rankings ? Is it possible that Nadal wins French and gets exempt from hard court masters and other slams without penalty ? In the worst case, he can just tank them. What do you think ?
