You guys do realize that there is a five year age difference? Why would Nadal have as much experience as Fed, and have played all the people Fed has played in his years on the tour? Don't Nadal, Djokovic, Murray and Gulbis get time to acclimate themselves to the tour, like Fed did? At their ages Fed was doing zilch. You all's logic is very strange.
When Fed beat Sampras that one time, you are saying that he automatically became his peer. Had Federer maintained his momentum, it still wouldn't have been a fair assessment as Pete had more time on the tour, more experience, and more savvy. That would be an illogical argument for Sampras and Fed, ergo it is an illogical argument for Nadal and Fed. Just because Nadal beats Fed regularly
I see you bring this same stuff time and again.If you don't mind me asking,when did you start watching tennis? You do realize that there's no one absolite rule for when players mature? For example Courier had his best years at the age of 21-23,Chang won his only slam at 17 years old,Becker also won his first slam at 17(wow the field must have been tremendously weak then according to your biased logic)and had his best overall year in his career at 21(even though he didn't finish number one cause he had the consistant machine Lendl ahead of him),Borg won his first slam at 18 and was burned out by the age of 26(that was 8 years of very high level of tennis,people here wrongly say he didn't have longevity,he definitely had,it's just that he matured very early),Seles was crazy good already at the age of 17,18.Then you have complete oposites like Lendl,Navratilova,Rafter etc.
Fed won his first slam in 2003,Nadal who is an earlier bloomer than Fed won his first slam in 2005,that's only 2 years difference.Sure Nadal is Fed's contemporary just as Becker was Sampras's contemporary(similar age difference).Look you can say Sampras is much better than Fed and similar stuff(I couldn't care less about all this GOAT stuff between Fed and Sampras,as far as I'm concerned neither one of them is GOAT)but I will always strongly disagree with you about Nadal not being Fed's peer(and I'm positive a lot of neutral,objective tennis fans will as well).
Also for experience factor,in tennis much more often than not young age will prevail over experience(Fed over Sampras at Wimbledon,Safin and Hewitt over Sampras at USO,Sampras over Lendl and Mcenroe at USO,Fed over Agassi at 2003 TMC).
One last thing,between Sampras and Fed there is a 10 age difference while between Nadal and Fed is half that number.that alone makes it a much different situation so it's not comparable IMO.
