Thats a very interesting thing to come up with. Thanks!
How about doing a 3 year post career slam comparison. It would include one slump-year for both of them... (2011 for Fed - no GS) and 2012 for Nadal (Relatively). Just curious.
I'm curious to see (In future, in about 4 years) on how Nadal's post-prime will shape up to be. I'm sure it can't be as good as Fed's but can he do a decent job with his playstyle?
If Federer's resume has holes, then everyone else's has more and bigger ones.
