Does anyone actually new blood inside the slam winner's circle? Personally, I don't - I wanna see Nadal and Federer fight it out for the history books with one of them hopefully winning the most grand slams in history for another 200 years or so. If someone else won a slam, or god forbid, several over these next few years they would stand in the way of that happening. As it stands, I don't see anyone challenging Nadal for any slam for the next few years. This year's Wimby is probably Federer's last ever shot.
