When I see Nalbandian play a match like today it makes me shake my head at how good he could have been. Same for Safin of old. The two of them are as talented as Fed, Nadal and Joke but they lack the work ethic for conditioning,the comittment to the sport and the desire to be the best. Opposite those two are Hewitt and Roddick who have the fire and drive but not the weapons. Fed, Nadal and Joke combine all the traits while the rest of the field is lacking in one or more areas.
