I am not liking Nadal's move. He is a momentum guy, and he is killing his own momentum with this long of a break. He is a 31 year old guy in great shape with no injuries...He could probably train for 5 hours today if he had to. There is enough time to rest between RG and Queens.
This shows me he has his priorities and grass is not up there. Or maybe he does not want to demoralize himself in case he loses to a nobody at Queens.
Either way, personally, I am not liking this move.
