Now that Agassi has called his retirement, it could be the time - maybe a bit premature - to put his career into historical perspective. In short: Is he top five all time material or top ten? His achievements are not easy to evaluate, i think like Hoad or Becker, he is quite difficult to rate. He had longevity, but also a few years in between, which he virtually threw away. His greatest achievement, mentioned by players like Mac or Lendl, is his full card set at the majors, on 3 different surfaces. But can it make up for his relative short time at years end Nr.1? OK, he was longer Nr.1, of you count all placements year long. But imo, can we rank him above say Connors, Lendl or Mac, who were all Nr.1 for at least 4 years. His longevity reminds one of Rosewall and Connors, who also had a great return game, but is he in their class? I would rank him top 15 ahead of Becker or Edberg, but not necessarily top ten.
