Sampras was the best player for 6 years. Agassi was arguably the greatest returner ever and possibly the best pure ball striker too. Federer has 17 open slams and 300+ weeks at number 1. Djokovic has the best court coverage ever (not even debatable). Safin, nalbandian, etc, was/is considered unbetable when playing their best. Nadal is the clay goat. Your point???
