I apologize, I missed the you love Rafa thing, but c'mon, if you love him you should know he would not lose to freaking Rosol at Wimby if he was at full health.
Of course he shouldn't have lost that match. Just like Murray shouldn't have lost to Chardy in Cincinnati either. Does that mean he was injured? No. I'm not saying Rafa was at his best that day, but to use his knees as an excuse every time he loses a match, is ridiculous. Rosol played really great Tennis in that 5th set and Rafa still moved comfortably enough for me not to think he was in severe pain. Trust me, they all have their niggles that they play through. When you demand so much of your body something always hurts.
You are a true Rafa fan. One that sees both flaws and pros in the guy.
Too bad that You must spread some Reputation around before giving it to silver lining again.
