Andre Agassi is incredibly underrated by the TW Historians. One guy once tried to tell me that AA fell outside the top 30 all time. What? I mean, what more do you guys need? --8 grand slam titles --Career Grand Slam (Only one outside of Federer to do it in the modern game on different surfaces and not in a grass court park) --17 Masters Series titles (most in history of tennis) --Masters Cup winner --Davis Cup Winner --#1 Ranking --Great competition (the BEST) --Incredibly long career where AA was never made irrelevant (this guy competed against everyone from Mac and Connors to Sampras and Federer). --Olympic Gold Medal --And lots more This guy is easily top 10, and imo, top 5 of all time. Before you guys jump on me, I'd like to point out that people who know tennis agree with me--and not you (yes, I'm talking to you, TW Historians). Both Mac and Wilander listed Agassi in the top 5 greatest player to ever play. And Tennis magazine ranked him at #7.
