I'm as tired of hearing about Federer's back as I am about Nadal's knees. I'm starting to believe that these two guys have the same PR manager. But seriously, if Federer loses are we going to hear more about the chronic back injury again? The other disgusting part is that we almost only hear these consistent excuses exclusively from the top players. If the injury is not that bad, don't bring it up, don't take an MTO, don't stop play, don't talk about it... This back excuse was first used when he was 26 or 27, will he at least get over it like Nadal did his knees?
