money.
easy cash. but it hurts Rafa the most.
Roger has an easy playing lifestyle and he is 35 so he knows his days are numbered on the tour in terms of being a factor at slams.
Rafa is the only one who can challenge Djokovic which will have to be on clay.
so why waste away by going from country to country playing in meaningless exos on the hard courts.
he has clearly said for 5 years running now that there are too many hard court events. he just finished saying that WTF in London should have been on clay.
the bottom line is that he has to be able to win on clay in order to win big at slams. he has to make a difference on the red clay in 2016.
that is where the resurgence starts for him. he has to go out there and just do it.
