You are very much right. But i think He does not have much opposition. Not a player of even Goran Ivenesivic's calibre, to test fedex. There were great rivalries between Borg - Tanner connros and MacEnrow, lendle and wilander , Becker and Edberg, Sampras-Agassi-Ivenesevic. Though I very much like the way and the grace with whihc Fedex plays, I long that some one who is consistant with his serve and avoids unforced errors will emerge and be able to beat him. Sampras was very very special too.
