Obviously there was a dig intended. But that is disappointing and disturbing to hear. As I said above, he has to protect his clay season, though. If he's injured, I don't see what there is to discuss. There are a few Rafa fans here that do play directly into the "if Rafa lost he was injured" trope, but not all of us. Folks could ignore the others. That's why it goes on for 12 pages, frankly. But the Fed fans are getting nearly as bad with that, and have always leaned hard on "if Fed lost he played crap," anyway, and not so much credit to the guy who beat him.
As to the commentators bringing it up in the first place, as
@Federberg mentioned: Did anyone see Kyrgios' tweet after the Djokovic loss? He said that he loses and the press slags him off for being inconsistent. When Djokovic lost to the same guy, they speculated on injury or distraction. He said: Maybe Kohly just played great tennis. He's not wrong to point that out. When the greats don't play great, it's the commentators that start it with looking for reasons why, and then the so-called "excuses" start.
