Murray always played retarded vs. Nadal - no strategy whatsoever. Just idiotic losses in the Slams in 2011. Lendl has helped to give him a better strategy vs. the big guys. I'd favor Murray in most circumstances.
Poor Rafael ran as fast as he could, but it was the talent which he lacked and not the fight. All fight and no talent is the name of Nadull.
Roger & Pete - Offensive all-court genius. Nadull - Defensive pusher.
If Nadull had an argument for GOAT, it's that he got so far with no talent. It's like dragging a dying weasel across a long road. He gets there, but it's an ugly sight to behold. Nadull is a classless cheat, and a pretender.
Roger Federer(on Nadull): "He's one-dimensional, he always plays the same way."
