If we were playing equally well that day, I'd call it a draw and ask him to play dubs with me against my favorite opponents. I'd love to see how horrible my game is and who'd be the first to melt down. I already know my own game, so I wouldn't care about singles.
Dear Roger Federer, you've changed your game accordingly.. with your aging, and our expectations.. but you've got to remember you are RF. +!
