I didn't mean to imply the old "weak era" argument against Federer. But I know it's a sore spot. I really was just talking about Alcaraz being so much at the tail end of the Big 3, but having interesting contemporaries. I know with Roger it's a chicken/egg thing. Was the competition not up to it, or was he just miles ahead of them? Personally, I think both things were true. As you point out, some of the greats Roger faced were old, even if resurgent, in the case of Agassi. But he was too long in the tooth to change his game for Roger. Roddick was too one-dimensional to ever compete with Roger. And don't remind me of the magnificent, mercurial Marat Safin.
Yes, Rafa said Roger made him a better player. And he did. If you're potentially great, and you're chasing great, you'd better up your game. Same with Novak. They were up for the challenge. But there was a certain stutter-step to when they each started/caught fire.
I think Alcaraz has a number of contemporaries with potential. We'll see how it goes, and who pans out. Plus, is Alcaraz another Federer? Will he leave everyone in the dust? This we cannot know. However, at the tender age of 21 and month, he's secured his place in the HoF. He has achieved a certain greatness. If he stays healthy and happy, there is a lot more excellent tennis to come. I feel very good that he has Juan Carlos Ferrero guiding him, whom I believe is a lot like what Uncle Toni was to Rafa. A father-figure, a firm hand, and a calm, guiding force.
