Guga had his "prime"career cut short by injuries etc. By the time he achieved YE #1 he hadbecome a serious threat on HC and would have posed serious problems at AO and USO for anyone had he not been curtailed.
Guga played great in 2000 Masters Cup to clinch #1 (over Safin), beat Sampras in SF and Agassi in F. Damn shame his career was cut short by injuries, he was the only guy that made CC tennis entertaining to watch.
You think Roddick would be a fair witness? He played in all the slams in 2002 and played on the same courts until he retired. In his radio show, he said, "No contest. Courts when I started were super fast, later on, not so much. By 2007 or '08, courts that were once slick had turned into molasses."
Argue with that,
Did you hear it yourself on the radio or saw it written if some article? If it's the latter, could you post a link?
