I'm convinced something's going on with Rafa that has nothing to do with his knees. Since Miami (even earlier?) there have been rumors that something was going on in his personal life. This entire clay court season he's been flat. I barely saw his family at any of the clay tournaments either, which is highly atypical. Nadal News yesterday showed a news clip of him in Mallorca, practicing with no knee tape. I fear that someone in his family is sick, or something along those lines.
