Is Andre Agassi the best player of all time. At this point, I would have to say no. However, he is without a doubt in the top 5. You have to give Sampras the nod at #1. He has the most Grand Slams. I would place Rod Lever second, then Jimmy Conners #3. Andre is #4 followed by Borg. Andre may have less Grand Slams that Borg, but Borg never won all of them. Either did Conners, but the fact that he did win the U.S. open on all three surface does mean something. I know that there were a lot of great tennis players before 1960. However, the game of Tennis became an international sport in the 90s and 2000s that you can not compare modern tennis with the past. Everybody in the top 100 (in the mens game) can play. Something also to consider about Agassi. He has won pratically every major tennis tournament in the work. Not only all of the Slams, but he has won a record 16 Master Series tournaments, including 7 of the 9 (he has never won in Hamburg or Monte Carlo). He is also the only player every to win a double in Paris in the same Calender year (he won the French Open and Paris Open in 1999). He has an olympic gold medal as well (1996 Atlanta). One last thing, it is rare that an Athlete disappears from a sport for an extended period of time, then retuns to become more successful. John Mac, Borg and Matts Wilander tried and did not even come close to the same success that Agassi has. One last thing, how many majors would Agassi have one if it wasn't for Pete Sampras (who is the best of all time). Pete between Andre in 3 U.S. Open finals and 1 Wimblendon, not to mention the semi final and quarter final loses in other slams. Any thoughts.....
