Your poll is a total joke. Your opinion is not one which is shared by majority, Sampras used to overpower Agassi and Becker by his athleticism, Becker himself accepted that at his peak Sampras is a better athlete him hands down, that was Sampras's impact on his peers, Agassi as we all know was inferior as a pure athlete. Look at anyone from that era and see the speed with which Sampras moved to the net, how he leaped in air, how he imposed his power on others, his running forehands very nadalesque...he used to impose himself on others and he weakened in 30s because apart from fitness hsi thalassemia brought down his athleticism, started to take a toll on him. At his peak he was everybit a freak as Nadal was.
De Manure in the poll is another laughing matter, see the opinion of other posters in the thread, your view is not shared by anyone.
