That he cannot freaking break? It's possible.
At 2007 Roland Garros final, Federer converted 1 of 17 against Nadal.
At 2015 Dubai final, Djokovic converted 0 of 7 against Federer.
At 2012 Australian Open final, Djokovic converted 7 of 20 but he won the match in six hours. Is that then projecting for future?
At 2009 Wimbledon final, Roddick missed that volley against Federer. Was that on break point? He converted 2 of 5 then. But he is such an extreme case, does it really matter? Besides, it was more because he had no game to match Federer than being owned.
