Another topic would be if Nadal ends up with 4 or 5 hard court slams and if he ends up beating anyone of substances (eg- Federer, Del Potro, Djokovic, Murray, some others) would you consider him better than Agassi on hard courts despite that Agassi ended up with 6? I for one would. Agassi had joke draws to most of his hard court slams- both U.S Opens, and the 2001 and 2003 Australian Opens were the worst in history. And Sampras did not deny him as many hard court slams as people think, he was never winning the 1990 U.S Open, unlikely to win the 2001 U.S Open, and he could have been beaten at the 95 U.S Open by Courier or 2002 U.S Open by a better day Hewitt in the final too.
Most people rate Connors, Lendl, and McEnroe above Agassi on hard courts despite that they all have fewer hard court slams.
