Lol when he's injured fanbois like you make excuse that his body can't take full schedule .there are two possibilities 1- Nadal is not injured whenever he loses
2- he gets injured by overplaying. I don't think Nadal was injured last year in fo match , if he was injured he would have been cautious with his schedule which i don't see. Nadal critics are right about his injury claim at RG.
In other words, you don't know enough to advise Nadal on his schedule.
Also you got your "possibilities" wrong.
1) We know Nadal is injured, because he's been diagnosed.
2) Nadal has said he's always played in pain, so that means he doesn't reduce his schedule and be cautious..... he plays in pain, and if the pain becomes too much sometimes, then so be it.
And I've never had a problem with Nadal's schedule..... because I know he'll get injured at some point and that will give him 2 or 3 months of rest, and then he'll come back and win.
That is the nature of knee tendinitis, that is also the nature of Hoffa Syndrome, and that is also the nature of his foot defect.
All 3 of those conditions flare up when you play a lot, and then become more manageable when you rest and receive treatment.
So there is no reason to be cautious..... just play when you are relatively healthy, and take a break when you are not.
