Most of them won in a Nadalless/Rivalless era and feasting off injury of his main opponent. Nadal isn't scared whether Roger is in the draw, you can't say that the other way around
I hate to join in this stupid debate, but you do realise Fed won the majority of his slams WHILE NADAL WAS WINNING SLAMS, right?
Nadal's Slam period: 2005-2012
Fed Slams from 2005-2012: 13
If you're good enough to win a grand slam, even if only on one surface (Nadal, 2005-2006), then you can't just say "Nadal was crap back then". Let's not forget Nadal was in the Wimbledon final in 2006. For God's sake, he got to the 3rd round of Wimbledon in 2003! More than most of our current 'up and coming' players can do. Raonic, currently #13 in the world, and everyone's dark horse to win a slam soon, bailed out in the 2nd round of this year's Wimbledon.
