You know, one thing I don't think gets mentioned is that maybe Nadal just isn't that into it anymore. Maybe he's satisfied with what he's accomplished and doesn't really have the drive or interest to fight his way back, especially through the larger obstacle of physical decline. Maybe he's thinking, "I'll give it another go this year, see if I can win one more at Roland Garros, and then coast through the season and call it a career."
That article that Carol posted mentioned that Nadal seems rather resigned. I almost wonder if he is even at peace. I haven't watched any recent matches, but I'm wondering if people see a player who is struggling internally, or if they see a guy who is just going through the motions.
In other words, he might simply not want it anymore, or not want it enough.
It's not impossible. For me, Rafa hasn't been the same player mentally since he won the US Open in 2013. The intensity and fury that drove him through that historic summer then evaporated somewhat in the autumn, and he's never really gotten it back. Physically, he hasn't been the same since his back went in Oz. He's fit now, but he's not the same.
And who can blame him if he was satisfied with his career? 14 majors, 27 MS titles, 2 slams each on grass, clay and hards. He's put every ounce of sweat and pain into being the great player he was, and when he was at his very best it could be generally said that he was the best: but it's a rough game and players get weary of travel, practice courts, gyms, drills. Matches. Travel. Pressure. It all adds up. In recent years he's been forced to the sideline through injury and he's used the time to flop off his yacht and swing his honey girl around in the warm blue Mediterranean waters, and who could blame him for thinking, it's okay to enjoy life a little too, now he's gotten the taste for it?
That's not to say it's true, but it's certainly a possibility...
