If federer could have only:
known he could not beat rafa on clay and thus tanked almost all clay semis except for the 09 RG when Rafa was knocked out, and then quit overall after 2010 AO he could have had +H2H against Djoker and Murray (and a near even record against rafa) and 16 majors.
and somehow i think that would've been better to a lot of the people here on TT than him staying around, making more clay finals (that he lost to the clay freaking GOAT!... do you realize if Nadal were just a great clay player and not the Cgoat that federer would have 3 french open titles and a CYGS?) and winning more masters and even another major.
Fed's prime did not meet up with Djoker's prime or Murray's prime... if anything it's shocking that way post prime federer can still beat and or make it REALLY uncomfortable for these prime 25 y.o. players.
If Federer chooses to continue playing, then yes, he's going to end up with a -H2H against the other top 3.
Should he quit?
what's better... quitting now to preserve H2H? quitting in 2010 to preserve H2H? or getting possibly another major (which is entirely possible)
