Exactly as saying Fed played in a weak era. Anyone can see watching his game he would have been great in any era.
To add further proof to that Fed decided to come back at #1 well past his prime at 31, in the supposed "stronger era".

And talent is subjective, Murray may be more talented in your eyes but if he doesn't have the results, it doesn't matter. He is not on the level of Federer/Nadal/Djokovic and Hewitt/Roddick continue to be more accomplished than him. I think Nalbandian is more talented than a lot of players who have won slams but in the end, it doesn't matter.
