The question I pose to you is this: What is Nadal's current record, realistically, for this year? 43-5. Let's count the losses, shall we?
- Against Federer, Wimbledon Finals
- Against Hewitt, Queens Semis (Withdrew, presumably to save his body for Wimby)
- Against Clement, Marseilles Semis
- Against Blake, Indian Wells Semis
- Against Moya, Miami R64
Now, investigate a little into Fed's yearly stats... 56-4. In short, the difference in loss numbers is nigh upon negligable. Admittedly, Fed only had 1 of those losses on hard. However, this year, Federer and Nadal have only MET on hard courts once this year.
So to say either is that much better than the other is just foolhardy.
Fed <? Nadal, Nadal <? Blake, and Blake < Fed. It's not hard to argue.
