Lol.....Paul Annacone. Are you f-ing serious? The guy who helped lead Federer to a 3-7 record against Nadal (1-7 outside of WTF where Nadal's game sucks) and waste numerous opportunities at Slams?
Paul Annacone is a bland tool who is responsible for one of the worst Slam stretches in Fed's career and Fed wasting huge opportunities (I actually agree with Darth on this).....Ljubicic has a much tougher mindset and is a far better coach for Federer to have. Annacone is a weak-minded pansy and it is no coincidence that Federer kept losing to Nadal while Annacone was his coach.
Annacone is a good fanboy for Nadal (and frankly whoever is winning at a particular moment in time). That is exactly what he is made for. He is one of the weakest-minded coaches I have ever heard, in any sport.
Hiring Annacone was maybe the worst decision of Federer's career.....it cost him a few Slams.
You have some weird theories, and blaming Annacone for what happened to Roger between mid-2010 thru 2013 is surely one of them. A little context to your claims above is worth providing. Roger was 29 when he hired Annacone, and his h2h v. Nadal was already 14-7. He lost the SF at USO to Novak just weeks into their partnership, but it doesn't matter, because he would surely have lost the final to Rafa, anyway. He did win 3 titles by the end of the year, though, including the YEC. 2011 was much more the year of Novak v. Rafa, so I'm not sure what Annacone could have done about that. He won 4 titles, including his first at Bercy, YEC. In 2012 he won 6 titles, including his first Wimbledon since 2009, and the YEC over Djokovic. In 2013, he hurt his back early in the Spring, and that was really it for his year. Again, nothing Annacone could do about that.
And all of this has no bearing on Annacone as a tennis expert, which was A-P's point. In order to discredit AP's point, you went after Annacone as a coach, which is not only pointless, it was misleading. Sorry for the interruption, folks, but that was too ridiculous to let lie there as if it were true.
