You don't think Nadal was consistent in 2013?
He had 24 top 10 wins... so did Novak...
Fed only 15 in 2005...
I just don't agree that ADuck was degrading the slams, all he's doing is trying to make a point that the player that won the most important titles had a better year. So it's total nonsense.
If Fed had won 3 slams in 2005 and ADuck was trying to argue that Nadal's extra Masters title makes up for it, then that would be degrading the slams...
