So what is your point? This was a comparision of Djokovic and Roddick. Anyway on your last point, Nadal has done 10 times more damage to Federer's career than Federer to Nadal's, in fact Federer is almost irrevelant to Nadal's career. Federer cost Nadal probably 1 slam, while Nadal cost Federer about 8 or 9. Nadal's problem was always the field, Federer was never an issue or big worry.
"Unlucky, unlucky, oh yes," uncle Toni said. "If there wasn't Federer, perhaps Rafael would have been No. 1 for four years. But with Federer, that was impossible."
