^The argument is the same as it always is. That's why it has a thread. I'm not a proponent of "weak era" theories, and that's not what I'm trying to say, but I think johnsteinbeck and federberg oversimplify it by saying that if you win a lot you jack up the other guys numbers. And you, Broken, keep insisting on the talent on offer in Roger's early domination, which is true, but partially only in theory. Yes, Roger specifically kept Roddick from being a 5-slam winner, not a 1-slam winner. But he's not the reason that Hewitt, Safin and Nalbandian didn't do better. They had their own reasons.

El Dude's post #49 here. There was an anomalous gap between all-time greats (6+ Slams) between Sampras and Federer, which gave Roger a space to slide into, with his amazing tennis. I don't think this denigrates most of what he's accomplished, though I think it explains one reason he had so many weeks at #1. But I think it's worth considering, in the more subtle parts of the argument, that Nadal, Djokovic and Murray have had very stiff competition at that top of the game, which is mostly where they've dealt with each other. And of course, Roger has still risen to the challenge. But it's disingenuous to exclaim about Roger's earlier competition as talented, when he didn't have to face them as regularly, and not nearly as many that were make-or-break finals, even excluding Slams. I know the notion of a "weak-era" is tainted, and, as I said, I'm not a proponent. I'm only saying that I think the argument is more complicated. Roger probably got a leg-up at the beginning of his domination. It's not a terrible thing to say, given that he's kept making the most of his tennis.
