he is going to have to take it easy in indian wells and let Miami masters go.
it is way the hell too risky to put in too much time on the hard courts before the single most important clay season of his life.
its over if the back goes in Miami.
people have absolutely no idea how hard it is for him to dominate clay starting in monte carlo. it takes absolutely massive effort. and he has been doing it for a decade.
I hope he takes your advice.
