I must say that I find one person completely underrated on these boards and in general: Andre Agassi. Now, I'm not a particular fan of Agassi. I'm not that fond of him, I'm too young really for that era but Sampras was my favourite and is apart from Federer but look at what Agassi did! 8 Grand Slams Career Golden Slam 4 Austailian Opens 2 US Opens 1 Wimbledon 1 French Open 1 Olympic Gold Medal 1 Masters Cup 17 Masters Series (more than Federer and Nadal) And 31 other tour titles giving him a total of 60 titles. He's also third all time leader in earnings after a certain Mr.Federer and Sampras............ This guys done it all, and as much as I don't like him, you have to give him credit for it.
